Vodacom ruined my entire life

I am writing this with a very heavy heart . Everyday I regret ever answering that call because it ruined literally my whole life. Last year October I received a call from a Vodacom consultant offering me a wifi SIM card contract. To be honest I never needed it because i kept telling the guy that i already had a wifi at home but the guy convinced me and made sure to call me for three days straight, I finally gave in because he said their sim card has more data. The sim card got delivered really fast the problem was that it was not registered, i tried everything to get it registered i even have proof, i tried to contact the consultant but i was put through a machine, i tried to contact Tobi, i went to two different Vodacom stores from two different cities but they both told me i need to register it online because i purchased the sim card online, the guy that signed me up for the sim card never ever bothered to every call me to check how the service is till date, they charged me for a SIM card they clearly can see is not registered, I reversed the debit and since that day my credit score started decreasing and decreasing, im so broken because this whole year i missed out on school because i couldn’t get any loan and before the Vodacom saga i had offers, you literally ruined my whole life and this thing has had a negative effect on my life i cry almost everyday. I wrote many emails i have proof because they started sending emails demanding money and threatening my credit score, every time i sent an email i never got any reply, early this year they have me false hope by referring me to a consultant and they gave me a reference number and said i will be helped in less that ten days but guess what? Exactly till date i never got help. Last week they sent me an email saying i have less than 21 days before they take my account to Debt Collection Agency??? At my age?? Blacklisted??? For something i was forced to take and is clearly not working? Can’t they see from their system that the SIM card is not working? Is someone not doing their job??? I rep**** and guess what after they asked for all the information i was referred to Tobi??? Tobi??? I needed a consultant and you referred me to a robot thy couldn’t even help me again?? I have been advised to go to ICASA and file a complaint because I cannot pay for a service that doesn’t work, i have anything Vodacom with everything in me, I couldn’t even get help last year even after downloading their app it was always glitching, I regret taking that call and before this incident I always loved Vodacom, and they don’t care about their customers coz if they did they would have called to ask how im finding the service since he convinced me and i hope phone records are kept.
