Since approx march of this year ive been reporting my phone line as faulty and BT have been agreeing theres a fault and then saying theyve fixed it, but they havent, finally reported it again last week and a tech came out and said there was water in a junction box about 2 miles away. So should i contact them re compensation, as now hes fixed it (on their 5/6th attemp) my line is quiet and my internet actually streams. Where as before you couldnt hear anyone and a 5 min youtube vid took 15 mins to stream.
Call them, ask to speak to disconnections. Tell them your story and then say you want to move to another provider. Disconnection departments normally have the lee-way to offer discounts to encourage customers like you in order to make you stay. You may well find that you end up with a discounted connection fee/line rental fee.
If you just 'complain' they will try and say sorry, then write you a letter saying sorry then nothing.
It's all about customer retention. It's just a shame they don't it through providing the service they say they do in the first place.
