After about 5 hours, I got internet for about 30 mins before it cut out. The speeds I got were 30 down and 1.2 up - which was way off the estimate.
I then called up Zen and we logged a voice fault. Openreach fixed that the next day, and my speeds went up to 40 down and 2 up. After another day, I called Zen again to say the speeds were not what my estimates were and they agreed that something wasn't quite right. They logged a broadband fault with Openreach and again, that was fixed the next day too.
I came home and did a speed test and it turned out out I now had the full 80/20, with the modem syncing at 80000/20000. Since then, I've had about a week of internet and the speeds are consistent at every time of the day, I don't seem to get any slowdown and the latency is great. The connection is rock solid and stable and I consistently get 8.5mb/sec download speeds.
Zen were great at sorting out the problems which were not caused by them in any way. I always got through to a member of staff after less than 5 minutes and I was treated with respect, there were no scripts and everything was resolved fast. They have even refunded me for the days where I had no internet/phone.
This is EXACTLY why I chose Zen. I imagine if I'd chosen BT Infinity, I would have had a huge amount of hassle and they may not have even dealt with the broadband fault at all. I am glad of my choice.
