mtn ripped me off, no refund

I bought a BIS bundle(R59) from Mtn early Monday morning(07/27) and waited a while for the service to active. When that didn't happen I called the company's customer service and the consultant told me the service is incompatible with my blackberry z3 and that I will not get a refund. My concern is that there is no notice posted informing prospective buyers that some models of the phone are exempt from the service. The consultant I spoke to advised me that I am also not the first to suffer such a loss. So if it has happened before why hasn't any steps been taken to ensure clients are able to make informed decisions? If this was costing them money it would've been remedied by now. Mtn has unduly benefited from myself and others like me...
