Pathetic Vodacom

My upgrade was done in March and I still don't have a handset which I am still paying for! This the second time that I am complaining about not just the service but overall treatment by Vodacom. I have just recieved feedback regarding my query and was informed that I will be getting the same model again for the third time. I reiterated to Vodacom that I am not prepared to take the same model again. Clearly Vodacom doesn't care about the level of service and customer satisfaction. Let alone health and safety should the device blow up or cause serious harm or damages. I am not prepared to liaise with a consultant but want to speak to someone from management or has authority to make decisions. Vodacom had responded to my last query but I rep**** to their response and haven't received anything thereafter. Pathetic service from one of the leading service providers in SA!!!!
