Bad,WORSE CUSTOMER CARE

I m still struggling to get my account in order with vodacom since July2020.Vodacom listed my name as bad player and that my account is in arrears when I still wanted to give them business and upgrade one of my many contracts I have taken with vodacom.They were continuing to deduct 17000.on my account for the contracts which I requested vodacom to reverse.This has led to my account in arrears.I went to vodacom store in polokwane on the 23rf December and asked them how much is my arrest.They told me is 3548.i paid the arrears and also requested them to activate the debit order from the 15th January 2022. which is my pay day.Today I was called by vodacom Savannah indicating that they will not upgrade one of my contract because my account is in arrears after few days.I m frustrated pls help.
