After 2 years of using BT, I have had no issue with the connection it's self, until I came to cancel, where BT lied saying they had canceled my services and payments but continued to take money, it took another 4 phone calls to stop them taking money and they agreed to repay the money owed.

However they then backed out of that saying that my service was still active and I should of contacted them soon, even though I had canceled. Would highly recommend avoiding as they are not below lieing to your face and changing their mind, backing out of agreements that needed to be made because they decided to lie in the first place.
