Unacceptable service

Don't have anything to do with Netstar their service is unacceptable. I had issue with their device draining my cars battery after struggling to get hold of them I had to pay R287.50 in advance which I did via EFT. I had to nag for them to remove it. Two weeks after I paid they finally remove the device. On the 1st of September they took another R287.50 out of my bank account which is unacceptable and shows incompetence on their side. I DON'T have account with them for more then a year.
