Broken brand new Hisense side by side fridge

Purchased a Hisense side by side fridge from Game Menlyn on 21.3.26. The store representative didn't have stock and checked at other stores. Fridge was allocated at Wonderpark. Delivered 23.3.26, switched on 25.3.26, packed items in. Called them on 26.3.26 following a move from one place to the house where the fridge was standing. Reached Earl on 26.3.26 just before 9am and was told the rep will call me back who works with appliances. Thereafter I called twice and no answer. I eventually reached someone who didn't want to give their name and was provided with an email address. I sent everything through about what transpired and the receipt. Friday 27.3.26 morning i called back again and reached Voster Chauke who indicated he wasn't at work 26.3.26 and never received the message. I requested the call to be escalated and was told he just got it this day. I insisted. I explained I shared an email also. Back and forth and a technician called around 4 to say they'll come the saturday morning before 9. He was here before 9am and checked the fridge was didn;t have gas. He issued a document and said we should go to the store. The first experience it was indicated deliveries aren't done over weekends, which we didn't question but thinking that going to the store will expedite the refund or return which was unsuccessful. We requested to speak to the store manager, who came but had a somewhat arrogant attitude. Words were exchanged and we were told technicians don't advise on store because there are processes. Initially he said he was told the story but later on he claimed he didn't know the full story, yet I sent an email and follow up. As much as I understand processes and procedures, no apology or acknowledgement of the issue was given. Rather almost like they were expecting us and decided they will treat us in whatever way. There was a Kagiso/Karabo who alluded to the email and hence I felt like they were expecting us. Fast forward to 30.3.26 now a full week, I called and follow up. I'm now told no credit note has been issued. I highlight I'm not at home every day, so I'd like to know when it's picked up. This is truly very unprofessional and for paying over 11k, the service is absolutely horrible.
