I filled in the paper work with my correct banking details a few days after that I got a call with a voice message: Good day this is Tracker please note that youre account have not been paid press 1 if you would like to update your account details after I talked to the lady at the accounts department and updated my banking details and arranged that I would make the payment into their account after that the same voice message phoned me again so then I phoned the owner of advanced Auto he told me that the lady that works for him will sort out my problem he phoned me back and told me the problem have been sorted out a week after the incident after i already paid them via EFT and send the proof of payment through to them I got a Message stating avoid suspension of youre services make a payment or phone the number to update youre account details I need to say this is the poorest service ever
