R1 000 over charge

Issue 1. I recently had a change in ownership of the unit that was installed, from a company into my personal capacity mid September. Tracker then charged me a pro rata on my personal account. I then asked that they credit the company the pro rata because the unit had been paid for in advance or don't charge me for the remainder of Sept.

Issue 2 The package I took is R119 per month. I called more than 5 times before month end of September telling them that they've charged me incorrectly. Month end comes and I am overcharged by R1 000, YES ! ! ! R1 000. When I called them today, they say that they can see the request for credit but has not been actioned, this query has been sitting with them for 10 days. They will send a request to Finance ( which I am unable to talk to when I call) as well as the credit controller who is also unavailable.

I tell you, because of this, I am moving the company's entire fleet. How difficult is it to charge the correct amount
