Pathetic service

Worst company to deal with, I have been trying to cancel my contract with this company for the longest time. I have been back and forth on emails with Kirsten and requested to cancel. I paid 1700 on the 28 of April 2020.i have been receiving calls that I missed a debit order how do I miss a debit order of something that I canceled. She said that that my cancelation fee was used to pay in arears.and in order for me to cancel again I need to pay 1700 yet again, pathetic. I'm not even using the device anymore, the car is long sold yet I find myself having to fight to be removed off their system
