Bad Communication

In 2018/19 I made an arrangement with Vodacom to pay my account up to date, when it was up to date paid, they will help me to cancel some of the accounts that I have with them to help me to be able to afford the account I am having with them. End of July 2020 I managed to pay the account up to date, I called them and they unlocked my account, then it seems that all of my accounts have been upgraded without my knowledge, I explained to them that they need to help me to be able to afford this account, then they said they can only place me on a Covid-19 relief, but the amount is more than R3000.00 a month, I explained to them that I can not afford it, I phoned several times during August 2020 Vodacom to get someone to help me, I have sent 3 e-mails to the legal department after I have made use of the Mobi abb online, I have received the ref numbers but did not get any response the end of August 2020 I have received a bill of R4664.26 !! I don't have that money!! of all the accounts I am having with Vodacom I was only using two of them for the last 3 years and since last month only one !! I have phoned on 2020/09/07 again and a lady was willing to help me to downgrade all my accounts to make it affordable for me until I can stop some of my accounts, and the system stopped her and demanding a payment, that I don't have, and have been telling them since the beginning of August 2020 to help me Please!!
