Telkom being Telkom

Telkom somehow allowed someone to **********ly open two new contracts on my account. I picked this up only two days after it happened and went into a service center where I was told I had to get an affidavit and return back to the store which I did the next day. I was then assisted at the store in Melrose Arch and told that I would be contacted within 72hours, it has now been 21 days and I have received an invoice for my account which is over R600 more that I will have to pay, I have also tried contacting the "Social Media Forces" yeah... no surprise that I'm not getting a response from them either.
