Cell C don't care about there customers.

This is the second time I wrote to Hello Peter about Cell C. I've bought a laptop at cell c in November 2022. I only used it twice and I'm battling to get it fixed. I managed to get it booked in at cell c repairs in September 2023, where first they could not fixed it because it was blacklisted for ***** in 2022. after many calls and no help from cell c, I eventually got all the paper work done to unblock the laptop. Then they phoned me and said that they are not allowed to fixed it I must booked it in with Platinum warranty... So I'm back to square one.... Platinum warranty does not want to book it in for repairs, they need a tax invoice from cell C. Which Cell C say they can't provide me with one... So that means I have to pay for a laptop that I can't use. Where do I go from here??? When I phone customer service they transfer me to repairs to be transfer to sales to be transfer to contract department just to start over again...
