Incorrect Billing on my account

Dear Vodacom, you are an ABSOLUTE joke of a network! How can you authorize a debit order of R38971.16 on my account when my monthly payment is R380?! Obviously you have ********* working in your collections/accounts department!!! And then further to this...... what are you doing about this?! I now have debit orders that's bouncing on my account and I don't even want to know what the penalty fees will be with ABSA when one's account is in a negative by that amount!?? This is also NOT THE FIRST TIME this has happened. 2 months ago you added 2 new numbers on my account to the worth of R3000 WITHOUT MY AUTHORISATION!!!! And then I ended up having to pay the penalty fees MYSELF because Vodacom CANNOT GET THEIR **** TOGETHER?! And you did ABSOLUTELY NOTHING about the situation... NOW, don't tell me that I should phone the ***** line because I have and unfortunately your ********, illiterate staff, that can't even speak proper English, is of no help whatsoever!!!! I need to speak to someone that has the authority to at least do something about this problem!!!!!! Jeez, put me on the line with your CEO, I'll give him/ her/ them a piece of my mind...
