Issue still not resolved

I reported the fact a few days ago that a sim card had not yet been received for an upgrade that I did to a data contract. I then received the sim card but they were then unable to do a sim swap. I have since had 2 agents phoning me, each time having to go through the security check, and then being told that they are unable to process the sim swap and the problem has been escalated. Well, to date no one has contacted me. I am now getting to the stage where I wish to cancel all contracts with CellC, as each time I have to contact them for any assistance I end up going to this forum for assistance.
