*********** stuff and lack of product knowledge results to poor customer service

Good day I need your help with my case with vodacom, I had 2 contracts with vodacom one ended in April then the other one was supposed to end in January 2022 so now my problem is that before April I was paying vodacom so well without any hustles so now by April a lot of things started going wrong over charging saying there are whatsapp bundles that I do not know of saying they were activated using ussd I struggled to see to it that I get that account back on track because I didn't want a bad credit record then they told me because the accounts have been joined I do not even know why did they join them now even after the term for that other phone ended I was still paying for it regardless because they say if they are combined the arrears of that other phone will always affect the closure of the other contract I have been calling vodacom so many times at times they even block my number to prevent me from calling I struggled to make ends meets until I paid everything and was left with one contract then I called in on the 1st of July and spoke to them to ask for a settlement quote and I did ask about any extra charges the consultants that I spoke to kept on saying the same thing that a settlement quote would include all the extra charges because I called in late on the 1st not in the morning because I knew they still need to allocate airtime for that phone so they did send me the quote then I paid it 4days later then emailed the proof of payment to them when I called in their cancelation department they kept on assuring me that after that settlement there won't be any payment I have to make to vodacom and 2 of the consultants said that to my surprise days later I get an invoice saying I owe vodacom 300 for this month I called in a week ago and the lady I spoke to said she will escalate it to her manager and they will give me a call they never did now I called in today the consultant who I spoke to today speaks of a different thing saying the quoted amount is a "premature cancelation" which only covers the cancelation fee and not the interest and installment for this month I asked her how come because when a settlement quote is being generated all the interests and installments have to be included why did they exclude it she also said she will escalate to her manager so as he can call me in 3 days same story as the last time and they never do I mean the 25th are near and that 300 that they say am owing them is gonna jeopardize my cancelation because of such incompetence that is why I wanted to pay them off and part ways with vodacom but now they keep doing this to me I dont have anymore money to give such incompetence on their end they should account for it or the 3 consultants should account to this money and pay it because clearly they gave me a wrong settlement quote. Please help me I am tired of the mistreatment iam receiving from vodacom
