Worst service ever

I bought a Defy microwave from house & home on the 21st September 2021 and was advised that it has 2 years guarantee. The microwave was working very well until recently, beginning of June we started having a problem with that microwave,it was no longer warming food at all. We then called the store at Goldfields mall where we bought that microwave and we were sent from pillar to post. Eventually we were told to bring that microwave in for repairs and we did on the 19th June 2023. When we got to the store we had the microwave in a trolley from the parking lot as it was heavy, we were assisted by the same lady who sold us that microwave in 2021. Her name is Jennifer, she looked very annoyed and nit interested in assisting us. We then explained what was wrong with that microwave, she took it out of the trolley and as she took it out she dropped it on the floor and the security guard was so shocked and another store assistant. The security advised that she must include that she dropped the microwave but she refused and that really shocked us as we wanted to know if it didn't cause any damage. They took the microwave in on the 19th June 2023 and the following day we got a job cut number on the 20th June 2023. On the 28th June 2023 we were called to come and collect the microwave and when we got to the store,we were told to wait because the is a mixed-up with paperwork. We waiting for 2 hours and they were now rushing to assist me as it was knock off time. They tested the microwave for few seconds and it made a funny sound but was advised it works. We were not happy with the sound that came out of the microwave but we took it anyway. When we got home we tried warming food to test the microwave but the sound got worse and the microwave smelled like a burning tyre. We went back to Jennifer the following day and she advised that she will call us, we waited and waited for her call but she called few days later to advise on when we should bring the microwave again and we took the microwave in again on the 5th July 2023 as instructed by Jennifer and later on the day we got another job cut for repairs. On the 11th July we were called to come collect the microwave. On the 12th July 2023 I went to the store and spoke to the store manager regarding my concern with this microwave, I asked if I encounter a challenge with this microwave because Jennifer dropped the microwave how am I going to be assisted. I didn't get a solid answer regarding this matter. I left the store and on the 13th I got a call from a very rude guy by the name of Andrew who claim to be a senior manager at Defy of which I doubt his position based on the way he spoke to me and his poor customer service. Andrew advised that there's nothing wrong with that microwave and he said I won't be credited regardless of the branch I will go to. He mentioned that in order for that microwave to be tested and fixed again I have to pay R420 and mentioned he has been a manager for 30 years of which I don't understand how is that relevant. I asked me to send me a written confirmation of what he told me regarding the repair of the microwave and rudely refused and hung up the phone in my ear. After the call ended I got another job cut that my query is resolved and completed. I am really not angry at the service I got from Defy and House & Home branch in Goldfields mall Welkom, their customer service is very very poor and their staff is the worst people you can deal with, their rudeness and unprofessionalism will put the companies name into disrepute.
