Poor service

I had a bad service with OnAir TV in the sense that they don't respond to either query or question that one have. Last year i enquired as to why don't they put my payment record on my account as it puts my rating low on my Credit Score: they didnt respond, let alone acknowledge my request. Lately, they send note indicating that my subscription has reduced, but they are still deducting the same amount. I sent an Email requesting clearane of what is happening, they didn't responded. I sent three follow ups, still no response, yet they are taking money and need support on their business. What a shame of a business
