Complain - Unfaithful dealing on contracts

When I added the second vehicle to my policy, the premium for the 2 vehicles was supposed to be R358 as per telephone agreement but every month R379.34 gets deducted from my account. When I inquire I was told that the issue has been resolved but still the higher amount gets deducted. Upon further follow up, nobody answers my emails, they just get ignored as they are taking my money every month the don't care. I asked them to go back to their the phone records and refund me back the difference but this has not been done.

If Netstar can't hold if end of the agreement it must say so so that I look for another vehicle tracking company. The worst company that does not even have a dedicated complaints line to show that they don't care.
