Sim Swops

I did a sim swap on 2 data bundle sims on the 30th of June 2015, According to MTN the sims are active but they still don't want to register on the network. after numerous complaints to the employee that helped me the only response i receive is that the issue is logged with MTN and that i should phone the customer care line, I can not get through to them. I paid R136.80 a sim swap which is ridiculous. <br> <br> MTN can you please get this sorted.
