I also got confused with their overlapping explanation. However, after reading it properly I can safely assume that I will be paying £10 after a discount of 50% on the Sky Unlimited Pro package with Static IP. The letter also states that a charge of £5 is included for not taking Sky Talk + £2.50 for no Sky TV. I have had no further correspondence on the subject of migration.

The letter sates the deadline of 15th Feb 2014, if I wanted to change my mind etc. I am willing to let the service roll-over into Sky from Be before making any decisions and had a chance to assess the service. Although, Sky Talk looks good - considering I am paying BT the standard rental charge and don't make any calls. However, I don't know that I might be able to change the package later and still retain the 12 month no-contract get out in addition to being full LLU...

A change of product/package would trigger a new min term contract, no two ways about that, as it would with most providers
you could get line rental saver from BT with the free calling plan , or you could switch your phone provider to some one like Zen, or primus

Thanks. Yes, did not think I would get away without a contract! I was aware of Primus, but read some negative reviews. However, did not know Zen had a similar offering; although, the Line Rental Saver seems like a better option comparatively, if I choose to stick with BT.

I have been waiting patiently for the O2/Be handover to complete before taking any drastic steps and might grudgingly end up putting all the eggs in one basket, as I cannot justify staying contract-free vs savings any more. I am also aware that if I go with Sky all the way, then will have to play the retention/discount blagging game every year - not so keen. But if the savings are good and the service is above par, then I will have to bite the bullet and get on with it.

Hello Andrew, Thanks for the input.
Letter lost in the post? Perhaps, and I have no issue with that possibility.
However, as I said, four incidences of "less than joined up" communication is more than a pensioner should reasonably expect. It was sorted in the end, but it took far too long - and having to deal with a pushy guy, seemingly intent on signing my sister up to a product she didn't want despite a "calm, precise set of comments" made to him by me, was not acceptable.
The "o2" DD was cancelled (due to be paid on 20/02/14, and the "Sky" account commence on 25/02/14). My sister got an email saying she could have her services closed down immediately if she didn't make a card payment: this would have been for a "month in advance" despite the fact that for that month, she would now be with Sky! This was sent from SKY!
I phoned Sky, and they advised me that all o2 email traffic was actually being sent from the Sky address, as there were two "computer systems" that did not know each other!
He said ignore that email, the transition date is only a day or two further on, and ultimately o2 (Sky?) would send a pro rata bill for the few intervening days. This seemed logical to me, so I said that's fine.
My issue with the apologists is that o2/Sky should have dealt with an initial problem (missing letter?) the first time I spoke to them after the initial text - they didn't.
They then had the temerity to ask for £50-£60 - take your pick - which some TBB users think is fine: this only complicated an avoidable situation, leaving us where we were at the end.
I've been a quite happy Sky customer for 25 plus years, and have no axe to grind with them but, this merger/takeover has brought some avoidable situations/complications - if some TBB users are anything to go by - to the fore, and given that the average Sky/o2 user probably doesn't use or know of, TBB, then there is quite a possibility that many others - that the apologist are not aware of - that have been left to fight.
Generally pleasant people at Sky is my opinion - but this merger should have gone better.
Cheers, Les.

Sorry about the long ramble, but my initial post was merely meant to advise others that this was not a seamless transition for some: that some TBB users took up the cudgel is for their psyche, not mine.

Thanks for the input, Johnny. I hope you finish up with exactly what you want/need - but it could have been simpler!
Cheers, Les.

Indeed they have, Tommy, but for us it has been resolved - albeit with a lot of unnecessary effort! Cheers, Les.

As have we, Johnny. Cheers, Les.
