Incorrect Billing : ***

on 25th November 2017 I took out a contract at Games Stores ( Clearwater). I purchased a vodacom Tab amd the standard subscription was supposed to be R99 p.m for 24 months. I had contact Vodacom accounts Department to inform them that I signed a contract, wherein it was explained to me by the Games sale consultant ( sales agent no 25693) that I will pay R99 p.m but i will also be responsible for a pro rata rate as well, to which I agreed. When I checked my Vodacom account online i received an account of in excess of R3000 for the latter number. I phoned Vodacom accounts department to informed them to investigate why the account was so exhorbitant as i signed a contract for 99 p.m. .I requested that the line should be a top up line. I expected Vodacom to deduct R99 p.m and a pro rata rate as I had taken the contract on 25th November 2017. They informed me that I should go back to the store to speak to relevant salesperson to establish if the contract stipulated whether it was in bundle or out of bundle rates. The sales person did not explain to me that the nature of contract was that I had to pay out of bundle rates when the 1gig data p.m expired. when I lodged a query with Vodacom they indicated that they will reduce bill by R1500 but I was responsible for the remainder of the balance which was r1500. The rationale behind taking a contract for R99 a month was because I expected to pay R99 p.m. By the sales person not divulging the exact nature of the contract I was extremely prejudiced. Even the goodwill gesture by Vodacom to reduce the bill by half does not warrant me to pay 50 % of the balance. I should be paying less than R150 for the first account.
