Do not pay these ********!

Please do not pay these ******** any money! I have noticed that there have been a few people who have fallen for their ****! They phone pretending to be from Telkom, saying they would like to update your company details on their system at no cost. They then send a form which says FREE service and in tiny blurry text states that there are costs involved. 2 weeks later received an invoice for R9500. I realized it was a ****. Beware. They will also phone and pressure you for payment straight after they send the invoice. I was very direct with them and told them I knew it was a **** and refused to pay a cent, haven't heard from them since.
