Telkom Southgate passing the buck

Telkom Southgate has TERRIBLE service. Telkom changed my cellphone number on 17 August 2018 without my permission and then when I went to report the problem at the Southgate branch on 19 August, they could not tell me where the problem started! I had ported to Telkom from MTN in March 2017. The staff at Telkom Southgate told me FLATOUT that they COULD NOT assist me and told me to inquire with MTN as I had ported from there. All they did was check on their system ONCE and told me "this number does not exist on their records and NO ONE AT TELKOM (plural) will be able to assist". Also I did not know that my number had changed, it all happened without my knowledge and my family members and friends could not get hold of me for days. It became a huge inconvenience as I had to change a cellphone number I had been using for YEARS. All my personal documentation and policies use that number and now TELKOM is passing the buck to MTN. Telkom Southgate has unfriendly staff members who are *********** and their customer service SUCKS!
