MTN Pathetic service!

On the 21/11 I did an online application to upgrade my handset. A week went by and no one contacted me. 2 weeks later I called and was advised there was no stock at the online warehouse. I went to the Vangate store (CPT) where I was assisted by an amazing consultant Yusra who confirmed she had stock. She couldn’t process the order due to the fact that there was an open order pending. To date 500 calls and lots of airtime wasted the order has still not been cancelled after being told that it would be. I am so angry to the point that I could would gladly move my account to Vodacom. Your service is pathetic!!!!!! I want this open order cancelled by 12:00 Friday 18/12.
