Rentoza are ****mers!!

I just had the most infuriating engagement with a Rentoza customer agent. My phone subscription ended last year in November and I wasn't aware untill something said I must check on the app. So I contact them saying since my subscription ended last year and you have been deducting for the past four months there after. Either direct that money to the buy out price or refund it back so I can pay the buy out price. The person comes back and says they cannot do either of that because the extra money I paid is for the subscription.

I indicate to them that that doesn't make sense, how is it still for the subscription when the subscription is supposed to have ended 4 months ago. They still maintain that I'm supposed to continue paying because I still have the device, even though my contract has ended. Mind you no one wrote to me saying this or warning that since my contract has ended I need to either pay the by out price or I will continue paying. So I didn't see that my subscription had ended. They would continue deducting for another 6 or 12 months.
