Cartrack's patheric service

Service from cartrack is really apalling and ridiculous, i made arrangments with headoffice 3 weeks ago on a saturday to have my cartrack unit removed from my old vehicle and fitted into my new one, we made an arragement to debit the deinstallation and reinstallation fees over 2 months and i was assured the scheduljng department will contact me on the Monday to set an appointment, when monday came the full amount was deducted and no sign of cartrack ever calling me to schedule, the Durban branch never answers their phones when i try to follow up and head office always says that the durban scheduling department will call me, i follow up every second day and sometimes headoffice never answers as well, 3 weeks later i call this morning and finally get an appointment for Friday (lets see if they actually show up - i was promised in the past of a certain date and time but never showed). Really pathetic service from Cartrack
