Vodacom is a *******

I have had a vodacom contract for 3 years in those 3years,vodacom has only stuck to the contract agreement for 8months, and what the computer says goes. Vodacom needs to be shut down for this breach of contract. I dont need a computer to lie about my phone useage and there stupid tarrif prices.thanks Vodacom for makeing things hard to do my work,as I have a contract that costs me thousands,because I have a pre paid sim card im paying off for 3 years im done with this bad service delivery
