Due to the malfunction, I went and took the part that will be changed, but I hit the existing defective part with a hard object and saw that it was working, and I changed the part, saying that it is an impersonal company that takes the new part and receives a labor fee on it. I wouldn't recommend you to leave, leading of the trickster... I took the air conditioner that failed again after you to another mechanic, and the production year of the disassembled part is 2018, but the production date on the part I brought you to replace is 28/09/2024 . First, take a look at the date on the piece you bought from me, and then write me an answer.
