Very frustrated customer!!!!!!!

I am a very unhappy vodacom customer and I'm tired of fighting every single month... I am having endless problems regarding my vodacom accounts, in October someone called me regarding some new package, according to what I heard he told me that my monthly installment would Increase by about R80, I then agreed, at the time my installment was about R586. 02 per month, in November an amount of R843. 85 was debited from my bank, immediately I contacted customer care, a lady called me, told me she would do an investigation, a few days later she called back stating that the outcome is in my favor and my installment would be changed back to about R590 a month, I then agreed, but in December another R 839.98 was debited, again I was on the phone with customer service, who advised that I would be credited and I will only be charged the balance, but a few days ago I got another sms, this time stating that an amount of R1984. 97 will be debited from my account on 27/01/2022, I then sent the CEO a message and on 28/01/2022 I was contacted by Boitumelo Nhlapo, who promised to fix my account, allocate 2 gigs of Data monthly and reverse R2023 back into my account in the next 3 days, so far I have sent 3 follow up emails on different days and got no response from her or anyone at vodacom, they Are quick to debit your account but you have to constantly fight to get your money back, I am so frustrated and will definitely be taking further action against Vodacom!!!! I'm tired!!!!!
