Paying for non-existent service

Six day ago (12th) I complained on this site about the fact that I cannot receive SMS's and that all efforts to rectify the problem has failed. Vodacom did respond the next day (13th) by saying that the matter has been referred (to some unknown individual) who would investigate and come up with a resolution to the problem. Well, that was the end of it - in a week they have not been able to resolve the issue and re-institute a service which I, no doubt, will still have to pay for. In the meantime I cannot meet my obligations and do internet payments because I need a one-time pin number which is generated by the bank, which gets send to my number but then disappears into Vodacom's big black hole - never to be seen again. If I see the number of complaints lodged against Vodacom since my previous complaint, only six day ago, then, maybe, it is no wonder than they do not get the time to worry about \stupid"things like an SMS.
