DISGUSTING SERVICE- ABSOLUTELY APPALLED TO BE DEALING WITH VODACOM

I am absolutely disgusted with Vodacoms service. So I recently made a call to Vodacom on the 21st of February 2020 to have my debit order date changed to the 5th of the month as I have started a new job and I get paid on the last day of the month, when I had called the *********** staff member that I spoke to advised me that it is sorted, When I check my bill today, I see that Vodacom is now billing me for the Month of February and March and that the 5th is not available as a selected debit order day, it has been moved to the 9th of the month. Vodacom has also been *****ing R10 of my airtime balance everyday for WASP Content charges and for Vodacom Add to Bill charges, when i queried this, they had given me R 600 worth of airtime back, I really dont give a **** about receiving freebies from them. I budget myself accordingly and I dont have the money to afford a double debit now because of their dumb messups and lack of knowledge. I am very upset by how Vodacom has handled my account and I want this to be sorted out immediately, I am not prepared to have a bad credit record or miss debits because of pathetic and useless staff who cant even communicate properly. Vodacom is just a bunch of unprofessional *******, I cannot to end my contract with them!!!!!!!
