*****ing non-expiry Airtime to the amount of R3800

So, I got a call from Mpho at MTN to upgrade my contract, I was on a 750 contract. She said, I don't use all my minutes and should go down to a 350 contract, which would be cheaper than my current contract, which adds up to R899 per month...New contract over R1k per month. So I asked,what is going to happen to my carried over data (1.3GB) and my R3800+ that I have on my non-expiry airtime. She said, it will all be carried over to the new contract and would be available for the next 5 months. NOT. They just cleaned out my account. When the new billing month started, everything was gone. All the money and the data, this after I queried it again with Mpho...because I saw, the value of the money stayed the same and my minutes just dropped.<br> So, now I will cancel my contract and keep my phone as compensation for the thievery that is being committed by MTN at this stage. People, please check your accounts and your \non-expiry we can take it whenever we want airtime". Lucky me....I keep everything that get's set to me...even lies! And off-course"
