Still taking money of account

I have canceled my services with Affinity Health and after getting a conversation mail that all services have been canceled I still have debit orders going off on my account. I have mailed them to find out as to why the deductions are still going off my account and the reply that I got was that they are not the company that is doing the deductions. I have send them a screen shot showing them that it is them taking the money off my account ans still getting the replay that it is not them and it does state quite clearly that the debit order went to their company. I Asked for a refund for the money that was taken off my account and still no luck. I'm not the first person this has happened to and my wife had the same problem with the company. I would never advice anyone to ever use this company as they can't even get a simple cancellation correct and do a refund if they are in the wrong
