No assistance to resolve a matter since November 2021

I have been having endless back and fourth to resolve my account that has been paid up since last year November and service is still been blocked; and since then been asking to submit paid up letter and lift the block of account. I now received an sms stating my account has been handed over and due with an amount I have not received any communication about. I was with Vodacom for over 15years and since last year have had nothing but hell. They don't update their system after speaking to them nor have they helped to resolve this matter in any way or form. I am beyond displeased.
