Can you confirm that this offer was for only for a total of £8 on top of his monthly subscription and there were no other one off fees relating to either his old or new line.
If the ISP are sensible they'll not respond to this as you are not their customer.
I've been watching this topic grow, and it's upsetting to see a lot of bad information and advice being given. I spent a lot of time answering similar queries on the Consumer Action Group website, before illness took over and I'm now just a reader.
From what I've seen here there is a lot of missing information. Some that may have been edited out, some messages that the OP claims they've not had and seem this has continued as other messages from the ISP have not been seen. As both sides have verified, the OP is using a third party email service that the ISP has no access to. If this were me I would be checking spam folders and testing the address. It is a service I use myself and find it is usually reliable, hence the ISP assuming that email is being delivered, even without receipts being sent. The ISP has also pointed out that copies are kept in the OP's account pages of their website, which he still has access to.
I've seen posts that say the OP has confirmed that they have read through the entire website, which would include terms and conditions and the copy messages. If they have not read these then they have not read the entire website, but have said they have to the ISP. The ISP therefore can assume that the OP has read the messages fully, as well as the T's & C's.
I've always found that posts are edited to suit the way one party or the other wants them to read. The ISP has made a few posts, without going into detail in a public forum, that should have been of help to the OP but it seems their input has been in vain.
Those who are advising that the OP just ignore and walk away are missing a few points. The OP wanted to transfer their service to a new address, they were already a customer and a reasonably happy one at that. They did not look into the costs of transferring, which I have seen for myself on the ISP site. To assume that they could just up and go and carry on at a new address was obviously incorrect. The OP has entered into correspondence with the ISP and admitted to many things that would only serve to support their case if/when the matter is passed to a debt recovery agency.
Can I just refer everyone to a post by the ISP that should have seen an end to all this:
We had already said after the initial investigation we would honour the line install of £8.00 that he was quoted in the first place and scrub the other phone line activation charges including the charge for him to take his number, but he did not even agree to this. We have also made other offers all of these had been either turned down flat or ignored.
If the OP wants to carry on the dispute, bearing this offer in mind, they are set to lose a whole lot more than £8 (+VAT ?). They've already lost their Internet service and will now have to find another ISP and pay their installation and activation costs as well.
Regardless of the company address or trading name, a service was supplied and the OP cancelled their payment without giving fair warning. There have been issues with the actions of both sides but at least the ISP were prepared to forego the costs the OP said they were not aware of in order to resolve the matter.
My suggestion is for the OP to contact the ISP, accept that offer and move on.
