mislead

In September 2015 I was informed that my contracted needed to be upgraded in October. The contract I had was for the 5gigs data and 100 free minutes which was R375 pet month. I went to the Telkom in Parow where the sales rep informed me that if I don't upgrade I would only be paying R110.90 and would be better if I took out a new contract. So I don't lose out on the benefits. I then took out a new contract with a new number. After a month I was debited R817 rand for my old number and still today I am being debited R460. I've spoken to multiple call centre agents and they told me that it would be sorted out and I will be recruited my money. Till today my account is still being deducted and it's seems like nobody at the call centre can do a proper job.
