BT had the wrong address for us. We updated them three months ago and three months later we had our internet connection cut off with no warning. This is called 'slamming' and BT are well aware that this happens all the time to their customers. BT tried to charge us £116 for this. We spent hours on the phone being transferred to one advisor to another. We've used the online chat service in which the advisors were dreadful. This time cost my partner and me around £600 in lost income. We then had no internet for two weeks while we waited for Virgin broadband to be installed. (I would recommend Virgin over BT at the drop of a hat if you can get it.) This led to a further loss of earnings for my partner and me. Overall the service received was terrible, we spoke to many rude advisors who were defensive and had very poor communication skills. Luckily we spoke to an advisor who waivered the fee for us but we will never see the money lost due to loss of earnings and we will never get our wasted time back. Please avoid BT at all costs, avoid the poor-service monopolies.
