Account Cancellation

I was moving premises and wanted to move with them and was told there's no presence where I'm going and would have to cancel. I put in a cancellation request and was told that it's too late to cancel and would have to pay for the following month even though I won't be using the service. I paid for that month (Jul2019) and today I wake up to a debit order but had put in cancellation, I'm really upset at the pathetic service.

When calling the call centre they make you wait forever and still cannot assist, this is utter nonsense!
