SellDirect misleading and dishonest sale

Misleading and dishonest information regarding the package sold to me and now my line is locked and the stupid lady who I was complaining to today had no idea but instead told me that my line was locked due to unpaid Telkom contract of which there is no contract that it's unpaid and the other number that she says it's unpaid is working but the one sold to me is locked. How possible is that because I believe if telkom were to lock or suspend the line, they would have suspended the old one and not the new one I got from them. Initially when I took out the contract the sales agent informed me that they are going to give me 2GB data, of which that was the main reason I took out the contract. When I checked balance, the contract is 500MB all inclusive and 314 MB telkom mobile data available. The sales agent actually **** to me by telling me that I am going to get 2GB. Now they suspended my line and told me I have to pay R450, but haven't made a single call on that line. That is unfair marketing tactics they are using. They lie so that you take out their contract and after finding out, they come up with stories
