Hello,
I'm interested in this becasue I am thinking of changing my ISP (currently not BT as it happens).
If you have not already done so, read carefully the agreement you have signed. On reading it, are you still of the opinion that the level of service you are experiencing falls below that which the supplier promised?. I cannot offer a legal opinion but, in your situation, would certainly feel aggrieved by such regular interuptions.
Talking with your supplier is all very well but you really need to communicate in a way that provides you with a record of what has gone wrong and when. Only then can you present this to BT and say the level of service is not to your satisfaction and that you require a resolution to the problem. All this needs to be achieved is a realistic time frame and BT needs to be aware and accept that this is your expectation. Would 28 days seem reasonable?
OK, so they may have been trying from what you say. But what progress have they made and are they going to continue in coming weeks and months. In the meantime you are still a disatisified customer paying for an imperfect service..
Bar other replies to your post, do some research (connection permitting) of how to complain about provision of services falling short of your reasonable expectations. I did so regarding some products last year having been initially fobbed off. I politely and firmly said that I considered it was a supplier problem rather than mine under such-and-such legislation. A satisfactory resolution soon ensued.
No need to resort to the law - pretty damned expensive and probably would cost more than the value of the remaining contract - but useful to know where you stand. Your local CAB might be able to provide some guidance.
Having said that, are you new to broadband or only BT? If you are using a wireless connection, may be there are other users near you that may interfere with your channel. Then there are the usual avenues to investigate; BT's infrastructure between the exchange and your supply point; the quality of lines and equipment connections around your home.
I hope your service improves and is satisfactory. Meanwhile - and it is a pain - record everything you can. Include letters, phone calls and engineer visits that all support your contention that BT is not delivering what you thought you had contracted to.
Apart from cable, I believe the other ISPs will be using BT's infrastructre, so I cannot readily see to whom you would migrate if your problem is not sorted out. Assuming it is, and that you are not at fault, it may be worth asking BT for make a gesture of goodwill by allowing you a payment holiday for a month or two.
