Unable to Cancel Contract - Promises Not Kept

I called in on the 6th of May to cancel my contract as it was the end of my contract.

I was however still billed that month even though I was told that my last debit order date was April. I reversed that payment as I refused to pay for something I wasn't using.

I called in because I was billed and Kellin Samuel's informed me my contract was never cancelled. He was not able to escalate this. He said he wasn't able to see any call made. I sent a screenshot that I called in to cancel on the 6th of May.

The agent that cancelled my contract refused to give me a cancellation reference because they said it would be SMS'd to me.

I was then given an escalations email that doesn't exist.

I then turned to Twitter where I was told on the 31st of May that my contract was definitely cancelled and I wouldn't be billed again.

I was billed a random amount on the 1st of July even though I was told this was taken care of. I am not being given any answers. This cannot continue every month!

I am being told that everything is being taken of when it is not. This is just terrible service.
