Telkom has no customer service at Middleburg Mall

I have been to Telkom in Highveld Mall Witbank to assist me with a upgrade. Witbank Mall refered me to Telkom In Middleburg Mall as they say they cannot help me. So not sure why they even have a branch in Witbank Mpumalanga. This upgrade was regarding data contract. Telkom in Witbank Mall warned me that they do not answer there phones no matter what time you call this includes the Manager of the Telkom store in Middleburg. I tried calling the store in Middleburg but to my surprise no answer and I tried more than once. I then decided on Sunday the 17th Jan to drive to Middleburg as I resided in Witbank. A lady by the name of Rachel assist me. I told her my problem regarding my upgrade. She logged the complaint and gave me a reference number and said I must phone the next day. I told her how can I phone if your staff don't answer? I asked her for the stores number, checking to see if my save number was wrong. The number was right. I told her that I will test the number whilst in the store. Which I did only to find there phones unplugged. She told her assistant in Zulu plug the phone in think I did not understand. Her comment was when I confronted her \ this is not a call center """"
