Vodacom 4U and Vodacom Customer Care - Pathetic

I was at Vodacom 4U branch and took everything back (bag, router,sim, mouse, vouchers) Laptop and charger was given to them middle March already. This was on a new contract for a laptop on 1/3/20. The laptop was not working and 4U, Cape Gate wanted me to pay for a new ssd card. I purchased a new laptop - why must i pay for repairs or alternations? I have spoken to a few people at Vodacom Customer Care. According to them 4U is the ONLY people that can resolve this problem. I have made a million calls to 082 135, send a million emails to have this contract cancelled. Due to no fault of mine, Vodacom has blacklisted me now. My sons cellphone line has been suspended as of today - this contract has been paid for EVERY month. How can you just suspend a different contract? Still, NO ONE is able to cancel this transaction (4 months down the line). I need to apply for finance ( i informed you 3 months ago) still my name is blacklisted, and telling me i need to pay a lawyer to sort out this, is unacceptable. Vodacom 4U, Cape Gate messed up. now Vodacom Customer Care, is not helping or not wanting to help.
