Paying for a DOA laptop.

Hi. I hope someone will help me as now i am tired of being turned from pillar to post. Reference to my data sim renewal 063500****. On the 4th of April i went to the shop for an upgrade. Not knowing it will be the day i regret being Mtn customer. I renewed my contract and took Hp laptop with hisence router. When i got home the Laptop didn't switch on. Took it back to the shop Protea Glen mall where i have been assisted by one of your champion . She took the Laptop and i was told it needs to be checked. Few days later she told me she needs to claim it with platinum insurance. I have been patient. I would follow up until i decided lets cancel the deal since this laptop deal has not work out. In June took back the router as she said she will only cancell if i bring back the router. Todated 09 July 2020 three months later . I don't have the laptop. No router and the debit order is going through successfully. I tried calling customer service. I was pushed from one department to the other. To a point where the consultant has stopped responding to my queries. The whole intention for me to renew my contract was for my kids to have a laptop so that they can do thier school work safely at home. The whole of term two went pass. We are now approaching term three, i have no hope on the 25th with no fail debit order goes successfully. Im so disappointed. Don't know whom to contact for help. Can anyone help me😔
