Complaint - Bad Service MTN Mall@Reds

I did an upgrade on one of my contracts ( ***) on Sunday 1 December and got a 2 for 1 deal. My sim for the main phone was activated almost immediately, but the 2nd "free" sim is till now (12 December) not active. Eventually when I was there on Monday 9 December (4th visit to the store), I was told that the cell phone number has not been activated yet. All previous times when I was there, I was told the delay was due to the RICA being still pending and they have requested it again and it will take 2 hours then my phone will work. Yesterday (11 December when visiting the store again), I was told that they have been trying to get the number allocated to the sim fixed for the past 9 days, but MTN (as the branch cannot do anything about this) is still working on it. At no time during this 9 days (even when I went to there offices), I was told about this, or even received a phone call to tell me that MTN is still trying to fix the problems. Yesterday I had to phone 7 times to speak to the branch just to find out what is happening., with the only response "We have escalated your problem and we are waiting for our supervisor to give us feedback". No alternatives can apparently also be offered to me to get my phone working, but come end of the month, MTN will without any issue, take my debit order and I cannot complain about this. MTN really needs to make sure their systems are flexible and get their Customer Service up to scratch. Surely by keeping me up to date on a regular basis and not "promising" it will be sorted in 2 hours every time, I would not have been this irate with their service.
