Service usage limit change and loyalty points?!

At 10:30 todayI received an SMS stating that Im nearing my airtime limit? As I'm a prepaid customer this doesn't concern me, as any charges over the bundle will just be charged to my account by debit order, as has been the case for previous months.I was eventually locked and cant make any calls as of yet. I contacted the call center 5 times to have the issue resolved. Call one resulted in me being told that I had a limit of R9,56 set on the account which is why I couldn't make any calls...the limit would have been raised, but would only take effect within 5-7 days?! The second call resulted in me being told that the network is out of sync w.r.t limits, and that I should restart my phone and try again in 15 mins. The third and fourth calls were trying the same effort but with different agents. I spoke to Sephilile, a teamlead I might add, Eunice, Mpho and two others whom I cant bother to recall. What concerns me most however is the lack of knowledge on the systems, and the lack of an escalation path. Furthermore none of the agents seem to have any idea that I have spoken to the call centre previously on the same day and I just realized my loyalty points are gone.What is mtn doing?
