SIMs not RICA'd

On 18 March I bought 90 x MTN SIM Cards from the Customer Service Shop in Menlyn. The previous time I bought SIMs there were no issue at all to RICA my SIMs. This time the system just rejected the RICA and did not give a proper error message. Some of the SIMs did RICA that day. After a few phone calls, Marilyn eventually found out that you can only RICA 15 SIMs per day per individual. Which was okay by my, because what can I do to change it? But she promised the rest of the SIM cards will be RICA'd 15 per day until everything is complete. I am now on 21 April and my SIM Cards has not been RICA'd. I need it before Thursday, so I suggest you do something about it quick. I tried to phone every number available for MTN Menlyn, but could not get through on any of it.
