Worst customer service

I had requested that my account be canceled in September as I no longer have the vehicle and the 3 year contract had already come to an end. The female I spoke to on the phone confirmed that I would not be billed at the end of September as you pay in advance. At the end of September, my account was deducted for another month (October). To my luck, I cant even get through to the cancelations department after they have already taken my money. Absolutely appalling service. Definitely would not reccomend.
