My money is not good enough for MTN!

After 10 years with MTN, and under debt review for 8 of those years, they suddenly decide I am not allowed to upgrade my phone even though I have never missed a single payment or paid even 1 dat late for 10 years. They made 240k out of me for 10 years and this is what they do to their clients? No thank you! I will cancel my contract September and will never ever make use of MTN again or recommend them to anyone!
