Contract cancelled, Account still debited. 'MIWAY'

I have had car insurance at old mutual 'Iwyze' and budget insurance. The insurances were good and very helpful. I changed to miway, and it has been the worst move ever. firstly they debit at the wrong date.

Then they are still debiting my account even after cancellation of the contract. I have done 3 debit order revearsals, and 4 phone calls to miway to rectify the problem. They have done nothing, but simply continue to debit my account. I am even seeking the legal route, because talking to them is not helping.

All in all, they are the are worst insurance company so far, I have changed to discovery and I think so far I have had the worst customer service from miway.
