BT
By a long shot !
Moved house 5 weeks ago and went through their (house move) website 2 weeks prior to our house move. Filled in all the details and made sure everything was in order.
2 days before the move - contacted them again to make sure everything was in order. They said all was OK and ready to go.
Come the day of the move - no phone or internet. 2 days later - still no phone or internet.
Phone them to find out whats up - they say there was never any active BT line at this new addres (even though i know the previous owner - and have her BT number - and had already checked with her to see if she had BT and a BT box in her house) - they want £150 for a new line and i've lost my old number and the Broadband contract i have had for the last 7 years.
After another 6 calls - eventually getting to their complaints dept. I tell them that i'm not happy and am cancelling the lot. They then agree to give me a new phone line free of charge (with a new number i don't want - and a new 18 month contract i don't want) - I ended up eventually getting my old number back 3 days ago - exactly 5 weeks after i actually moved house.
I wasted £37 on my mobile calling them - and a total of 18 calls - most of them on hold and a complete waste of my time. Out of 18 calls - 2 were connected to British call centres and were dealt with relatively easily. The rest were dealt with in Mumbai - which is OK when it works - but the majority of the time with cases like this - it doesn't.
I had one Mumbai operator who blatently refused to do anything I asked - he actually kept repeating the stuff I requested and doing nothing about it (probably the most annoying thing i have ever encountered on a phone service) - if i had recorded it - it would have been a youtube sensation
But - there you go.
They also told the new owner of my old house exactly the same thing - saying to her there was never any active BT line at my old address (which had a BT line for 12 years) - they eventually backed down and agreed there was and re-imbursed her the £150 new connection fee also.
To cut a very long story short. There wasn't anything stressful about the house moving - apart from the BT stuff.
As I stated to their complaints division. I have paid them over £7000 over the last 12 years or so - for broadband and phone services
They have done virtually nothing for me - i've received nothing off them apart from the upkeep of a copper line.
To top it off - I have phoned them 3 times in 12 years - each time to complain about something they have done ( in 2006 I called about a double DD they took out - they said they would give me a free month - they NEVER bothered - In 2010 I phoned up to ask them to stop calling me to sell Infinity as I work shifts - They NEVER stopped calling and i ended up pulling my phone out when I slept)
So am I satisfied with my £7000+ outlay ?
Well I don't really have any other choice - same as the rest of the UK who relies on the monopoly infrastructure.
I could go on - but they are just shocking.
