The consultants at Vodacom are not doing their job

I would like to log a complaint against Vodacom consults and their collections department.I have a contract phone and my contract was ending in May.Because I lost my job i decided that I’ll pay upfront and settle the whole amount so that I can cancel my contract.So I paid upfront but didn’t cancel on the same day because I was in a hurry so I went to the store some other day to cancel but when I got to the store the lady who was helping me said the system doesn’t show that I paid 1600 to settle my Acc so I gave her the receipt for confirmation,so I still couldn’t cancel my Acc that day since it was still showing an outstanding amount so they had to fix that first and they said they will call me.After a few days they calle me and told me my Acc is due for an upgrade would I like to cancel or upgrade.I said no I am no longer working please cancel my Acc.Later after a month I got the data and airtime but I thought it’s cz I have to give a month notice before canceling but then even the following month I got the data and the airtime and the invoice that I’m owing I called them and asked them why cz I cancel my contract they then said it wasn’t canceled so now I was in arrears of about 1200 because they didn’t cancel my contract when I had told them to do so long time ago.I called them so I ended up talking to some lady from the collections department and told her my story she said I don’t have a choice but to settle that 1200 she will just convert my number from contract to prepaid so that I don’t get the services anymore and so that the arrears don’t increase and we also arranged for payment of about 200 rand per month for the next 6 months to settle those arrears.They closed my lines meaning I can’t make calls or use data I can only receive calls then said they are closing my lines so that the process of converting to pre paid can be quicker and I was told it will take 21 days.After a month I called them cz my lines were still closed and now they were telling me a different story saying it will be done on the 31 of July.mMy problem is that they closed my lines and still allocated the data and airtime and increased my arrears with around 500 rand and I can’t even use those data or airtime since my lines are still closed .Today is the last day of the month and I called them but still can’t get any help cz it seems they didn’t convert my number to prepaid and they might still allocate data and airtime for August which I won’t even be able to use since it seems they don’t wana open my lines.I don’t know why to do anymore cz I called a millions times and I’m not any any help from them I even when to the store and they told me I need to call them.amy problem is that I finished paying for my phone long time ago but now they wana keep allocating every month for the services that I can’t even use and expect me to pay the arrears .????????????????????????????????????????
