Still giving poor service as always

Upgrading my contract with MTN truly was the biggest mistake I have ever made. To this day I have major regrets. The 1st contract I got with them everything was perfect, then I was told I was due for an upgrade. Picked the phone I wanted. Everything was okay until my 1st debit order, the amount was completely different to what i was told my phone would be,i couldnt cancel the contract because they said its too late I just have to keep the phone and pay. Then they messed up my debit order,they changed my debit order to a cash payment without my consent and when I went to their branch where I got the contract they told me they can't help me I need to contact customer care,their service was absolutely mind blowingly disgusting and totally uncalled for,I had to sit there and be told how they can't fix this, how this isnt their fault,how i have to fix the problem myself. They were more concerned about my temperature than they were on a contract phone that i spend R1200 every month on. Whatever you do,DO NOT GET AN MTN CONTRACT. THEY ONLY AFTER YOUR MONEY NONE OF YOUR NEEDS MATTER. AS SOON AS YOU SIGN THAT CONTRACT THEY DON'T GIVE A FLYING HOOT ABOUT YOU ....AND OFCOURSE IF YOU DON'T PAY ATTENTION TO YOUR DEBIT ORDERS YOU WILL BE *****ED BECAUSE THEY CONSTANTLY HAVE ISSUES WITH THEIR SYSTEMS NO ONE CAN ACCOUNT FOR ANYTHING YOU HAVE TO RUN UP AND DOWN STAY HOURS ON THEIR CUSTOMER CARE LINE.
