Messed up account!! Paying for your mistakes!!!!!

I am very frustrated. This happened on my one number ***: MTN did not add my recurring 1G bundle in June 2015 as I asked for and charged me R1700 for data. I just had to pay otherwise my lines would be stopped! After 2 queries and reference numbers (*** and ***) nothing has been done to credit my account. <br> <br> Then the next month's account, July 2015, I was shocked to see they have charged me for a recurring bundle for the previous month (June) which I never got that month, hence the high data charges, AND a dubble recurring bundle for July. Sommer 3 recurring bundles for me! As well as charges for data use! I wonder how the heck could they charge me for data with so many bundles that were loaded!!!!! Now I must pay R1300 again for your mistakes!!!! This is ridiculous!!! <br> <br> I am concerned.... is there a lot of Zombies working at MTN nowadays??? I am certainly NOT going to renew any of my 5 numbers at MTN again!!!
