Miway Poor Service

I received a policy renewal advice in December for my motor vehicle and went for comparative quotes. All quotes were less than Miway so I asked them to requote. No quote was received. I went with one of the other insurers and instructed Miway not to renew. My instruction was acknowledged. On the 26th my account was debited with R20,408.41 as I pay annually. After spending some time with their call centre I received firstly correspondence that my policy had been renewed and then eventually cancellation confirmation. I was told it would take 7 days to refund the amount debited. I told Miway that was unacceptable and after further discussion and having to supply my bank statement I was assured the refund would be made as a same day agent refund. This morning no payment received. Very unimpressed with the service and long winded process to try to get my money back.
