decided to transfer our telephone and broadband from sky to bt this could not be completed by bt until mon 4th january 2016.bt failed to honour this date and failed to get us switched on until the 8th of january 2016. we made numerous phone calls to bt then they sent a engineer around unanounced to check the line. he was amazed and could not explain how this happened as all itjust a supplier transfer.from sky to bt everything was working with sky then it was not with bt.confusing i agree we got a bill on the 4th of jan16 billing us for the next month in advance.so we have paid for services we have not had.i contacted bt showed very little intrest in our dire situation.formally then submitted a complaint.only response we had was to aknowledge the complaint .someone would contact us within 7 days 14 days later heard nothing.a horror story from the start.any ideas what to do on this one how to aproach bt .not happy at all
