Poor Sim Swop Sevice

I had a sim which I used on the Afrihost APN. In January I had a problem with the sim. After attempting to do a Sim swop in February , March and April . I was told that the RICA was done on the Simcards but that the actual Mobile number was not RICA'd and after sending a copy of my ID and Affidavit they still could not do my sim swop. After my last of three attempts and finally being told to go the a MTN storeand get them to RICA the number and not the Sim I was told that the number was deleted from the MTN network. I now need to find my origiansl sim to have the number re-connected. This is poor service and I now regret ever porting to MTN which I regard as having the poorest customer service of all the networks I had to deal with. !!!
