Mondo and vodacom

Mondo have phoned me to migrate my account by vodacom.because my package was discontinued.they assured me that my installment will stay the same.that was not the case.now for 2 months i have tried to rectify their mistakes. I have received emails where they comitted to refund me.but to no avail.there is no credit in my vodacom acount.no feedback.i have to phone every time to find out whats going on.i ask for proof that the credit has been passed.but they only say that if was.but there is no proof.not even on vodacoms side. I do not know why mondo is even taking over my contract,as i still have to phone vodacom.if i phone mondo.then they transfer me to vodacom.the service is pathetic.they will surely make service providers loose alot of clients.
