Shocking Service and disregard for Customer Issue

I'm absolutely appalled at the disastrous after sales service provided at House and Home Richards Bay is providing, they delivered a malfunctioning Fridge in to our home December. The sales agent took a fridge off the store floor and delivered it to the house outside of its original packaging with no manual no docs related to fridge operation accompanied the fridge. She was informed outright that this was unacceptable and that we want a new fridge. To make matters worse the fridge displayed issues as it was not cooling properly and produced ice particles on the trays when it's a frost free fridge. I went into the store to complain in December and left when I was promised they will send a technician which they have not done to date (03 February 2021). During this time while waiting the fridge then deteriorated further started to trip the main Switch at the house. Food that was bought including meat products have gone to waste as they have gone rotten. When I asked them today to reimburse for the wastage they say their response is they don't cover compensation. This is even though they have not resolved the issue of the fridge or replaced it to date. The sales lady Nomiya has shown very little to no concern on this matter even though her manager Riaan asked her to arrange the technician to sort out the matter in December when I was at the store. She demonstrated a bad attitude and Disregard of authority to this manager in our presence. To date we have no functioning fridge and apology on delaying is not Enough as we've incurred a huge loss for them to shrug us off with not covered for compensation remarks. We want to be reimbursed for the meat and perishables wastage from this store or Shoprite Head Office !!!
