Bad Customer Service from Vodacom

Early in October, my husband, Robert, contacted David, in Durban re my unwanted cellphone. David promised to get Ram Couriers to uplift the cellphone, to credit my account with the cellphone instalment charged, and to put me onto a new package for Airtime only, (no Data) for my number ***. To date, Vodacom has not kept to one of these promises. I can only conclude that Vodacom does not believe in Customer Service
