Shocking!!!!

I have never in my life experienced such bad service in my life!!! I need to upgrade my phone, and notification was sent i can only do it on the 1st of June. Made my payment on the 1st of June, immediate payment to top is off. I phi<br> one the call centre Monday to after 25 min be cut-off. Tuesday i phone 45 min later i simply just could not hold on any longer. Wednesday i take off early from work to go to a branch. Get there, sorry we have no stock.. Jhb are striking. Sorry you cant upgrade because you didn't pay. Showed my proor of payment to the consultant and he allocated my payment of 3 days prior. He promised to process my upgrade on Thursday and had me complete a form. Thursday afternoon i walk in with no communication from this man. He started processing my upgrade .. just to say sorry it shows you haven't paid!!! Now it will take MTN's systems another 3 days to allocate a payment made on Monday!!!! What joke is this. I'm so upset, shocked. And there is no-one to talk to. No-one is taking ownership of this situation. You cant speak to one person at their head office, only if you are prepared to hold for two hours on the phone. Quick to take our money. Absent all the time
