New contract, but latest bill doesn't reflect it.
My broadband M350 contract was coming to an end on December 26th, so in early December I chose to renew for 18 months for £24 per month. I received two PDF files CSS100169900220, and CIS100169900238, detailing the contract.
Recently I noticed that my old contract had apparently ended but there was no sign of the new contract, so I used live chat to query it. After a lengthy discussion I was assured that the new terms would indeed start, and my payment would definitely be £24 a month continuing from the old terms.
Now I've checked, and I have been charged £63 with a bill date of 21st December, with no mention of the new contract.
Could someone investigate please? I feel as if my new contract has been lost somewhere, and in the meantime I am being overcharged.
