Disgusting service

I have a contract with this terrible service provider - Telkom. They have billed me R500 more than what my current bill is. I have spoken to 3 consultants and all of them say to go to the Pavilion store and speak to the manager. I am currently here at the store and the store manager is off and the 2ic Gwen is also not here. So the other alternative is to have another consultant help me. Please bear in mind I have been dealing with this from the 31st. No one is able to assist, no one knows what the hell is going on, everyone is just passing the blame... They gave me the incorrect contract, I asked for a top up contract but was given a post paid contract. No one even told me about that, no one explained that to me. I took out my contract with Gwen from the pavilion store. Can someone please call me??! Someone who is fully knowledgeable about telkom and their contracts etc coz I'm tired of speaking to people who keep directing me to the store when even they can't help me
