Bad service

I received an SMS on 19th of December stating that my subscription will be debited on the 22nd of December. I immediately contacted the MiX Telematics accounts department and talked to a lady, i explained to that although it's December my subscription should be debited as usual and she promised that she's cancelling the order.

Today being the 28th of December I received an sms from my bank that a MiX Telematics debit order returned unpaid. It's sad that i took my time to call in and arrange when they can debit and their employee didn't do a thing and my bank account is incurring cost of the unpaid debit orders.

Today i called to complain about what's happening and i was received no help. Cancelling the account is the only thing good for me
