Afrihost Bad Customer service

I am really upset as my Afrihost SIM is still not RICA'd and I have been waiting since the 29th of March for this issue to be resolved and today is the 10th of April and this issue is being thrown around like no one cares. When I call 173 it says that the sim is Rica barred and when I try calling MTN there is no way of speaking to a call agent so I don't know what to do anymore and when I try the Afrihost activation *141*774*1# it says invalid MMI CODE. And now it is being said The easiest and fastest way to get this sorted is to take the SIM to an MTN store with my RICA documents and they will do the RICA for you right there and it will be activated but it was supposed to be done the day I went to Santon to pick up the SIM. This is not customer service this is abuse.
