Poor service and " system issues"

After a number of months and 3 subscriptions, I can now honestly say that Rentoza has no idea what they are doing. They insisted that a double payment at the end of November be made as they were closing their office on 15 December and no subscription payments could be made after that. I then duly made my double payments but they still tried to take payments and sent me request after request after request for my December payments and had the audacity to lock my devices, No apology was received and I was simply told it is a system fault. Everything including poor services is blamed on system issues. I am going to be cancelling all my subscriptions as this is just apalling service.
