Terrible Billing Support, Billed for removed unit

What the hell is wrong with this company. They're quit to onboard you and take your money but afterwards they're useless. They removed my previous unit and now instead of billing me for the new unit, they continue to bill me for the old unit and the new unit. I've sent emails through and just get ignored. I called and finally got assisted, got a reply from Itikeng Maloke asking if I got my refund after getting the message Gidson logged a request to remove my old unit and refund me. Then they ask to retract that email and instead continue to bill me for this non existent unit. I don't actually know if they care about their customers, but if this is their support, I worry what might happen if something actually happens to my car. What, will they just ignore my emails and requests then too!?
