MiWay - Pathetic service and empty promises

I have taken out a car insurance policy with MiWay a few months ago. I was clearly told that my account would be debited at the end of the month and was sent an sms to confirm the amount that was to be debited from my account. It had come to the end of the month and my account was double debited exceeding the amount stipulated by the sms. I had contacted MiWay to query this who had listened to the call and had established that the fault was on their side and promised a refund for the amount debited above the amount the amount stipulated in the sms. I had sent them a copy of banking details and was notified that this would have been done in 7 working days. 7 working days had passed and I had not received my refund. I then had to contact them again which was 18 days after the query was lodged. They had not responded to any of my emails that I had sent. The matter was handled by a consultant by the name of Lefa who was a great assistance to an extent. I was then told that they are unable to refund me but in order to compensate me for the inconvenience they would offer me a 2 month holiday period which meant I would be debited half at the end of April 2016 and May 2016, I had agreed. Guess what...I was debited the full premium again at the end of April 2016. This has been an ongoing issue for over a month and I fail to understand why it cannot be resolved. Are staff members *********** or compulsive ***** to make promises and not keep them on behalf of your company? If it is such a mission to get a queried resolved regarding my account, how will you ever manage to handle a claim if I had met an accident? This is by far the worst service that I had ever received by any motor vehicle insurance company!!! Absolutely disgusting service!!! Regards Sabastian Gowthum
