Inadequate information provided whilst upgrading contract

In March 2020, my contract was in arrears with R980 as debit order had been reversed with the assumption my contract was expiring in February since I had got it in 2018 (buy one get one free promo). When my contract expired I was not notified and ended up in arrears of which I paid up on 23 April. I wanted to cancel my contract altogether with Vodacom because I had called countless times without getting good service. The consultant I spoke to on 23/04/20 convinced me to rather opt or airtime for R60 where I’ld pay for R35 so that I could keep my number and I agreed to the deal assuming my debit order will run through. Five months later I try using my number and notice service has been suspended, I check my emails and see that I’m in arrears with R395.96. To my demise, I call Vodacom and I was told that my account did not have a debit order since inception of the upgrade from 23 April 2020 because I had been in arrears previously hence it was converted to a cash account without being notified. When I upgraded my contract the consultant didn’t ask for my debit order details and I assumed it’s because you already hav my details and debit order.M my question is how is Vodacom going to fix my credit score which has a dent as the consultant who helped did not notify me that there is no debit order, it’s a cash account? Today when I called (***), I spoke to Thembi and she told me that the upgrade consultant is from Comit a Vodacom third party and I was not aware as I was in good faith that it was an agent from Vodacom. For some reason i knew this would happen, such a horrible customer experience
