ABSOLUTELY DISGUSTED , PATHETIC SERVICE FROM GAME LIBERTY MALL PMB!!!!!!

I am absolutely disappointed and disgusted with the service received from Game Liberty Mall. I had purchased a brand new samsung microwave 32l for R1999.00 on the 9/03/2021 with an extended optional warranty for 3 years which I had paid cash for R399.99, I have had numerous problems from August 2021 with the heating function as it did not heat up and did not defrost food items properly. It should take lenghthy amounts of time just to warm basic food items. I had contacted Game Liberty Mall floor manager Vaughn Reddiar who had stated that i should take the microwave to Blomeyers PMB to book it in for a service to diagnose the fault. Blomeyers booked the appliance in however i did not receive any documentation or job number regarding the booking. Two days later I was contacted by Blomeyers PMB to inform me that they are going to replace the "magnetron" as it was defective. A week later i was contacted to collect the microwave, however there was no documentation supporting the issue relating to the problem, I was then advised that all damage reports were stored systematically. After utilizing the microwave for about two weeks the same issue arose. I then contacted Vaughn to report the issue again and he stated that he will personally do a booking at Blomeyers PMB for the second time. I instead asked for a credit note to purchase a new microwave as it was within six months of purchase date and I felt that it was not worth repairing a brand new microwave for the second time. Vaughn stated that in order to credit me ,the microwave needs to be sent in for repairs on three occasions as this sort of policy from Samsung was confirmed from the Store Manager Mr Smith. I had no choice but to send in the microwave again for repairs. I was informed by Blomeyers a day after that the "megatron" had to be replaced yet again. I had picked up the microwave after the repairs was complete without any documentation yet again, the microwave worked for about three weeks and started giving the same issue. I had then contacted Vaughn to report the matter of which he asked to bring in the microwave to the Game store and he will book it in again for repairs at TM Electronics in Durban. I had still asked for a credit and was still informed that he cannot credit me as the appliance had to repaired for the third time as per policy from Samsung. The microwave was sent to TM Electronics and I was also informed by them that the "magnetron" was the issue. The microwave worked from collection date till September 2022, thereafter the same issue occured. I had taken the microwave to Game Liberty Mall and spoke to Rohan in managerial level whom had advised that Vaughn should have creditted me on the very first issue as it was a defective appliance. The microwave had been sent back to TM Electronics requesting for a credit but they could not credit me and referred me back to the store for a refund. Mr Smith had then referred me back to TM Electronics for a refund of which they stated they cannot do. I am really frustrated and appauled with the unprofessionalism and service received from Game Liberty Mall PMB!!! I demand a resolution to this matter as I cannot accept this defective microwave, I also require reimbur*****t for the extended warranty taken as well as my travel costs back and forth to the store.
