Billing Discrepancies and Poor Customer Services

I am beyond my limit with Vodacom at this point , I have spent the last 2 months on call which is equivalent to a couple of hours of my life wasted trying to sort out something that is an error on VODACOM'S side, I have lost my patience more than once with consultants who literally laughed at me , so great job on customer services from your side. I have an arrears on my account that IS NOT CORRECT. I am being charged for equipment I have settled, I have been pushed from pillar to post with the wrong information from the start of me trying to settle my account , I was then directed properly from a consultant in store which resulted in me settling only my devices and requesting continuation of my contracts, I did this AFTER I was invoiced which you will pick up on one of my calls with a consultant who advised I should get the settlement after the invoice, this was done and the devices paid instore, email sent to advise I want to continue the contract but have settled the devices. yet here we are down the line still charging me for the devices. It is now just over a 2k arrears, I am currently looking for a job and this is seriously impacting my chances because I look as if I do not pay my accounts, this is not true as I am paying it , but Vodacom refuses to look into my complaint , I have spoke to numerous consultants including a team leader and all I get is that it was escalated and then no word thereafter, I am at my wits end with trying to sort out this issue , It is baffling to me how no calls can be traces, no agents can be traced yet all of our information and calls are recorded? I am now done with this nonsense and will be approaching an ombudsman and legal assistance if Vodacom does not do their investigation and provide me with feedback before end of day today. I am sick to death of being a loyal customer to Vodacom but never getting the service you pay for. Sales VS keeping customers is clearly more of a "LETS MAKE MONEY BUT NOT CARE FOR OUR CUSTOMERS" narrative for Vodacom , and I will seriously be considering completing my contracts and leaving Vodacom after this. I WANT ASSISTANCE AND I WANT THIS SORTED YOU ARE NEGATIVELY IMPACTING MY OPPURTUNITIES FOR EMPLOYMENT WHEN I AM PAYING! MORE SO I HAVE PAID CLOSE TO 13 OR 14K JUST IN 2 MONTHS!!!!
