Vodacom a joke

Vodacom disappoint again. I have done an upgrade again after they convinced me not to cancel my contract. I was suppose to get a simcard with the phone which never arrived. The consultant that helped me messed up. A manager was suppose to phone me back nearly 24 hours ago and still waiting. Manager is Fiona Ndlovu from Vodacom Retention. Worst service ever. I think it might be after over 20 years with Vodacom split with them. Horrible horrible.
