Vodacom is pathetic

I am angry and disappointed with Vodacom. I was a loyal customer since the beginning. I had pre-paid and contracts. The last 3 contracts was my phone, my son's phone (He was still in school) and a data contract. When his contract ended When the contract ended they phoned me and told me I will now pay R50 less because I'm not paying for the phone anymore. Instead they more than doubled my payment - and no phone. When I wanted to cancel it they told me I'm in contract and can not cancel it. For a long time I fought them until they eventually cancelled my phone that was still under contract and put my son's number under my contract. More fights and eventually they fixed it but I was never compensated or reimbursed tor the money they took *******... When my data contract came to an end they pushed up my payment with R78. I wanted to cancel it and once again I was told I was in contract - I told them over and over again I did not sign or verbally agreed to a new contract. I've called them, sent e-mails which they never even acknowledged. During one of my calls the woman said to me mam we can not put you in a contract without permission because it is *****. I told her that is what I've been telling you for months now. She then told me to send a affidavit and 3 samples of my signature. I will not send them samples of my signature - if they could put me in a contract I did not agree to they can use my sample signatures to **********ly "sign" documents to proof that I agreed to the contract. I asked them for the documents or a recording where I agreed to a data contract that expensive and not getting a wi-fi rooter. Today I went into the app to see how much data and airtime I have left - they once again pushed up my monthly payment by more than a R100 this time - and I still do not have a rooter. I am sick and tired. Vodacom's service is pathetic and they now resort to ***** and theft to *******ly bound their customers. I want that data line cancelled immediately and I want to be reimbursed for .the money they *******ly stole out of my account for a contract I did not sign or verbally agreed to. I'm now telling my story here because Vodacom ignore my mails and calls.
