ABC review: LG French door refrigerator

I purchased a LG refrigerator at Lowe's in Surprise. The sales rep Steven "Senior" saw me looking at a Samsung and came over and I explained I had a refrigerator, the ice maker is broken and they don't make the part anymore. He recommended I buy the LG French Door. October 16.2024 I purchased it. Two months later the ice maker is working on and off.
After two attempts with LG to address the problem I call and ask to speak to the store Manager. I was transferred to Riley and when I asked to return the fridge he told me it cannot be returned, Lowes policy is you have 48 hours to return and item and it has to be in perfect condition. I have to turn to LG the manufacturer to return the fridge. I have spoken to five people at LG and they all say it is not LG's problem it is up to Lowes to return it and or exchange. I have their names, the date of conversation and also that one Fred in the Warranty Department told me all the people I previously spoke to "lied to me". He told me I needed to speak with Lowes Corporate office, it is their responsibility to refund or replace the refrigerator.
Yesterday, LG sent out a technician to replace the ice maker because I was told this was the process to try and get the authorization to return the fridge by the assistant store manager at Lowes.
Joey the Manager at LG agreed to send a technician out to replace the ice maker because they had already shipped a new ice maker to me as a result of a phone call I made on May 1, 2025 to LG. with Jesleeh.
Yesterday a technician came out and told me it was my problem because LG changed the Refrigerant to R600 in 2013 which means the space allotted for refrigerators built in houses does not allow for proper ventilation. So I have to figure out how to put a hole in my wall on my cabinets to get the ventilation I need to make ice! But he cannot guarantee this is the problem but he is pretty sure.
I believe I have a lemon and I do not want to keep this fridge.
If this were true why would my freezer work? Also, does the store not have an obligation to tell customers about this.
I believe I have a lemon and Lowes should give me my money back or exchange it.
I have documentation of all my conversations and who I spoke with during this whole nightmare.
