False selling and poor customer servise

I did an upgrade February or March and i was told that following month i will start paying the new contract amount because i explained that i was not going to afford anything more than that...so the lady decided to false sell to me just to conclude the contract and i sent an email complaining i did not get any response so it means Vodacom does not care about its customers so don't see why i should stay with the company that does not care about its loyal customers that is why their consultants are doing as they please
