Boksel service is a joke

Took out contract under the impression that they run on vodacom backbone as advertised on site. When I took out contract and tested found that it does not work on Vodacom at all. Tested at different locations with setup as per technical support with no luck. Then I get sms stating I owe them money as payment is in arrears, strange as on site you have to pay in advance to get sim and data and voice before you can use service? Then I am told R158 paid in advance was deposit that you cant get back if you do not use service for 3 months, even if site states clearly it is a month to month service.
