Incompetency

I have been with MTN with more than 15 years now. Never had I ever han a pleasant upgrade expieriance. There is always one or other issue. If it is not a stock shortage issue its system related. With the bad experiences I had in the past I thought I would be proactive. I ordered my phone almost 3 weeks in advance to ensure it is ready when I upgrade. The phone was ready. I received a call from the MTN call center about a day before I could upgrade. I distinctly told the lady that I have already made arrangements and I did not want anything to cause delays with the upgrade. I went to the MTN shop to do the upgrade and get the phone I ordered thinking there could not be any issues. Well unfortunately I was wrong. Eventhough they had my phone, I was informed that they were unable to process the upgrade because the person at the call centre did something on my account preventing anyone proceeding with the upgrade. I have given up with MTN they must be the most incompitant servece provider in SA
