consistently offline systems at Telkom

I have been wanting to do a sim swap for more than 5 weeks to no avail. Contract sim swap is only offered at the branch, no self service or online/ telephonic options. The problem is that every time I go to the branch at Richardsbay Inkwazi mall, I am told "the system is offline". What bothers me the most is the nonchalant demeanor of the staff at the branch, I asked to be informed when the system comes back on but I have heard nothing. I have traveled to the branch several times only to have this same experience and its costly and inconvenient!!
