If you are a bt customer enter your phone number and post results. http://www.dslchecker.bt.com/
Post connection stats from your hub/router
If the reason is because you live far from the exchange or cabinet then moving would be one option.
If you were expecting higher speeds or the BT checker suggests that you should be receiving a higher speed then you probably have some kind of line fault that needs investigation. If this is the case then you need to log a fault with BT.
Far from exchange....yes
No fault, just antiquated copper system.
Far from helpful response.....When am I going to be provided with fibre???????
The only people that can answer your question is openreach
