Not happy with what vodacom did to me

Vodacom debited R689 on my account on the 15th after kulsoem promised me that it won't debit until the finished the case , and on the 17th I called vodacom I spoke to Lerato who transfer me to her manager Peggy on request , I spoke to the manager he promised me that the money will be reversed to my account, on the 21st December I received a message that credit note was processed and even today the money is not in my fnb account , when I call vodacom they told me the money is in vodacom account and that's was not our agreement , do I have to suffer for something that I didn't do, I didn't do the upgrade and their the one who debited R689 instead of R249 in my account, I want my R430 back to my account otherwise I will go to the bank and reverse and pay them what I am owing them and the worse part of it , no one came back to me and tell me how far are they with the case, vodacom they ***** our money as to me that is a *****ing deducting more to my account don't bring it back. I want my credit money back to my FNB account today not to my vodacom account , as is not my fault that people did a ***** in my account u vodacom allow them, I want my money
