Vodacom is a bad provider and doesn't stay with the contract terms. *****ing money with a smile

Since December im trying to sort out my vodacom payment issues, sincetoday it has not been sorted. I had a double deal combo for 2 years (phone and tablet), 3 months before my contract ends they started to charge me for the double deal seperate, paying more for my contract deal. they just refuse to correct it. Now i upgraded the lady who did the upgrade said my deal is R498 pm now im paying R517.98 for the deal. All of these problems with vodacom inregards to contracts and payments. they change as they want to, doe not stay within the contract, but if you break the contract its hell to pay. Im really disappointed in the service of Vodacom and there promises that they do not keep. they are *****ing money from their clients with a smile on the faces. totally disrespecting their clients.

Can both these problems be sorted asap, i am gatvol for the poor service from vodacom. its always a struggle
