Received new SIM yet it is BLOCKED

Somerset West mall MTN do not answer phones. 1) I upgraded on Monday and I took out another contract (for some reason they couldn't complete the process) & completed RICA. 2) I came back on Thursday (signed forms), waiting in line again and again they couldn't complete the process. 3) Came back on Friday, received new sim after waiting 2 hours. Got home and the sim is BLOCKED. **I refuse to go into that store a 4th time (the store is HOT, the agents unfriendly and waiting time is LONG). There is no customer care, no communication and a very frustrating process. They also don't answer their phone ********** nor emails and MTN customer care cannot assist me because they cannot see whats happening (the store needs to assist).

Please can someone contact me who knows whats going on or just fix the problem and let me know.
