STALLING CANCELLATION

I cancelled my Get More subscription 3 months ago and was told it has been logged and processed but I'm still debited for it!!! I have been following up every month and the call centre agents transfer me to the cancellation department and nobody ever picks up then they say the cancellation department is unavailable and I must leave a message but nobody ever gets back to me. This has been happening for 3 months now and I just called again this morning and same thing! It's like the cancellation department is non-existent and they keep stalling my cancellation. I now believe it's just a tactic to get me to forget and let it go while they keep charging me for their useless service with non-existent benefits!
