Terrible customer service

I am an existing Telkom customer. My cellphone contract was due for an upgrade in November 2017. I did an online upgrade application on black friday, the 24 November. I received an sms and email confirming that my application was pre-approved and that one of the agents would call me back. No one called me so i tried calling the 10213 number as well as the 180 number almost everyday and no one even answered the calls. I have even left messages on the website for an agent to contact me and no one did. On the 04.12.2017 i received another sms from Telkom thanking me for choosing to upgrade my contract on the black friday special and once again informing me that an agent will be in touch in a few days. I received no calls from any agent until today, the 11.12.2017. The agent informed me that my contract is due for upgrade. I informed her that i was aware and that i had already app**** for the black Friday deal. I was told that i cannot get the phone on the Black Friday deal, as my application cannot be found on the system and that i can only get the phone on the package being offered at the moment. I am apalled by the terrible customer service. It is quite obvious that Telkom does not care about their existing clients. I had been with MTN for over 10 years and i honestly never received bad service like this with them. I am seriously considering switching back to MTN.
