Cartrack customer care useless!

Car track is honestly the worst service provider. I had a contract which matured (August) I asked for a new device to be installed today (Beginning of a new month). Im being debited for the old device even though i have a new one for the new month. The consultant who helped me(Lethi Futy) absolutely useless and rude. I have been holding to speak to a a team leader and nothing. Its such an inconvenience to part of them.
