Lack Of Timely Appointments, Multiple Techs, Not One Knows What Is Wrong

Had an appointment with A&E on August 27th, tech comes says part needed for LG TROMM Washer Control Panel not working. Tech says, Part should be here in a few days, call me on my cell phone, I don't live far away, I can come back to put it on, also call A&E and let them know part arrived to get an earlier return appointment to put part on. I call the tech and A&E, suddenly nobody is available, no earlier appointments available, trucks not in my area at all til 18th of September. Ok, so I stick with the appointment that the Tech made when he ordered the part.I stay home from 12-5:35p.m. because my window was 1-5 for service tech to arrive. I start calling A&E at 4:50 because the tech has not arrived and I wanted to see what his eta was and I wanted to speak with a supervisor to get the appointment scheduled as a priority for the next morning. I get hung up on 3 times, I get put on hold for 30 minutes at least 3 times by 6 representatives of this company.Finally I get an older sounding lady that apparently had made it past high school, born in America and she finally transferred me to a supervisor that tells me the notes on the account say that the tech showed up to my house at 5:45 and no one was there! Well duh! That is what i had been trying to inform all of them of! So ultimately the so called supervisor was just like I guess he's gone home now, I say Ok without doing his job and that is ok with you, that I did my part and he did not do his. Now I have to wait another 8 days for a service appointment that was not my fault that I was not at home. Pretty Much YES was her answer. WOW! Just Beware, as their techs are always late no matter what window you have and they always come with a Ridiculous song and dance, but don't fix a darn thing! This is the 3rd time on the same washer, same problem, different techs saying different parts needed for the same washer! REALLY! Assurance is who holds the warranty and contracts A&E to fix the problem. I called them back and they were less help than the A&E Supervisor. Yet everyone tells me they see where I called in several times to let them know I was leaving to pick up my kids at 5:35, was back to my house by 6 and was told that the tech did not call me, but called them saying I was not home at 5:45 when he arrived. Like it was my fault!
