I have just left BT. My contract was officially up on the 7th of June but my switch date wasn't until the 11th. I was told by an advisor that my services would stay live and I would be billed for the entire month, then received a refund after the services had been switched. I was charged £55 for services from 24th May- 23rd June. Today I have just received another bill for £16 for "line rental". BT are saying I cancelled the service while on contract, which isn't the case as like I said my contract officially ended on the 7th. Has anyone else been wrongly charged when switching providers? and is there anything I can do about this charge? Thanks.
