WORST experience with a service provider EVER

Just try calling them or emailing them, there will be no answer, EVER. I have emailed them many times to change debit order details. No response. I managed to reach them once and requested a debit order change. It wasn't done. Now I'm trying to reach them to cancel. No one picks up regardless of the option you select. It's like there is no one there, now imagine you have to call them to recover your car. Now I have a threat of termination and legal action via sms, and I still can't get a hold of them. No contact info, just an instruction to pay R147.00 or else. Worst part, I don't even have the car anymore but I can't cancel.
