Pathetic Service!

I am due for 2 upgrades on 1 Feb 2015. My current phones have crashed completely and I have called the call centre for permission to upgrade just 2 days in advance. I received the most pathetic service ever from a bunch of *********** *****s. After being a loyal subscriber for nearly 15 years or more this is how you get treated. They actually scream back at you over the phone. So much so for the respect towards your customer. I guess my lousy R700 contract doesnt matter to the billions MTN make. You have just lost one of the most loyal customers. Will be cancelling both my contracts after the service and the way I have been treated. Utterly disgusted with you and your pathetic staff MTN!
