It seems impossible to cancel a policy - shocking service

Shocking service concerning cancellation. So I tried to cancel my PPS policy with no success. Firstly my adviser cancelled it with no success. I then thought I would rather do it myself and went through all the procedures. Sent the final cancellation e-mail on the first of June. Debit order went off in July so I called in and the lady I spoke to informed me that they did not receive the cancellation form. She then went on to search under my e-mail address and informed me that she found the form and will process the cancellation. Now August debit order went off again and I called in again. Now I was told AGAIN that there is no record of my cancellation so I informed the consultant to follow up on my previous call as I was told previously that the cancellation will be processed. I was then informed that I will be called back as the system is currently not responding. Looking forward to receive that call. I was not surprised to see that PPS received bad ratings concerning this from other customers previously.
