Vodacom *****

Terrible service from Vodacom. We have had only vodacom simcards eversince but the service received today was disgusting. We had recently cancelled a contract n paid in full. Yet we had a debit order go off which was explained. But we apparently now have a random upgrade on data that was not done or authorised by us and vodacom cannot help saying and i quote " it coulr b3 ***** this happens" no information can be given with regard to this and we donot even have this number or sim to use the data that we apparently paid for and upgraded ... i spoke yo a consultant in the upgrades and cancellations department her name is Palesa. Very rude and unwilling to help. Making it seem like im asking too much regarding something i am paying for .. horrific service vodacom .. i wonder if other cellphone networks just allow ***** to happen and still tell clients that it does happen .. like should we just be okay with it ? Paying for something we donot have? .. vodacom had better sought this out .
