TOP UP

Am really disappointed with their service, I have 2 contracts with them and now am shocked why do I have a third contract with them. A consulted called me with the new deal of data that Telkom has, I was given the impression that it's a top up of the data that I already and I will only pay R124 for that new contract. I was told from R99 I will pay R124 only for the month. Now am shocked when I see my bill from R204.00 now they want me to pay R334.27 of which they have added a line that that I did not request from them to add. I was told I will be charged 105.00+124=R229 only. I don't why the top up came with a new number and a changed price. The other issue I can't even get hold of the Telkom contact centre for me to ask, and I understand. I want l clarity on the matter as soon as possible
