MTN customer service

I've signed a new sim only contract on the 16th February that comes with 20gb promotional data. The 17th February the queries started. My sim card was not RICA registered and my number was not ported when contract was created. So I had to RICA it myself at a nearby store and then was told that I can not port my number, MTN should have done it when they created the contract. I had to buy a new simcard, RICA it and phone MTN to make my number for life and to use my new simcard that I have bought as the contract simcard. Till today the 10th of March I'm still waiting for my promotional data, went back and forth with MTN, after 5 calls complaints that was locked with sms to confirm that it's escalated with reference number and been told int will be solved in 2-24 working days. I even received sms that it's been resolved??? I went twice to my local MTN store and been promised it will be resolved Yesterday 9th March??? This is now the new reference number, needed to say it is been the 5th new number ***. **** POOR PERFORMANCE FROM MTN!!!
