Worst upgrade under Mondo and Vodacom doing nothing to assist

I did an upgrade on 30 April and was assisted by a gentleman who called claiming to be from Vodacom. After few days i called Vodacom to check why my phone wasn't delivered, i was told there was a technical error. Waited until today and call Vodacom today only to be told by one of their consultants that the upgrade was done by Mondo. They gave me their contact numbers. I called them since 10:00 today until now with no response. Vodacom is also going around the circle now that i am asking them to do a reversal. This is the worst upgrade ever and i don't know why Vodacom is associating itself with such a company. I am still waiting for Vodacom to come back to me. I doubt that Mondo will even bother to respond my emails. Stay away from Mondo...................
