TELKOM is holding me hostage and will NOT release me. There is no-one senior enough to sort my problem out.

I went to my FNB yesterday to apply for a personal loan to join my children overseas for a family holiday, only to learn that Telkom is holding me hostage!! They have black-listed me for a device that I do NOT have. I've cancelled my contract with Telkom October 2017. They lured me with a special they had early March 2018. I received the new device and mobile Wi-Fi, despite daily promises of activation within 24hrs , after 3 weeks this device was still not activated. I returned the device to Watercrest Mall Telkom and handed it to Chanté in the manager's presence, I immediately cancelled my contract of THAT device that caused me such nightmares. I have emailed every person, in the highest position whose email address I could find, but not ONE person in Telkom is senior enough to sort this mess out. it's been over a year now and the manager of Watercrest Mall STILL tells me he had forwarded my case to the 'Right' person. I managed to get a CellC contract on the 'Telkom Cancellation Number of October 2017', but that was my last purchase or account anywhere, Telkom is holding me hostage and won't release me!!! I will NOT pay for a device that I do not own, never used, returned to their office without ever being activated, brand new in the box........... I thought maybe I should go camp in Telkom Watercrest Mall shop tonight and refuse to leave until they sort this mess (that THEY caused) out. maybe bring the press along for this rebel streak I have in me. I am now GATVOL..... I need a holiday with my children!!!!
