A&E Factory Service review: Frigidaire refrigerator (serial #ba [protected])

Above unit was installed January 13, 2022. It is a Pro Series unit meaning it's very nice and very expensive. Noticed there was moisture on the lower righthand back panel just above the vegetable storage area after 3-4 months. Did not think much about the moisture until it began to freeze. Then called Frigidaire who referred me to A&E. Service call #1 scheduled on June 17. Rep showed up timely and thawed out coils but did not replace any parts. Said give it a go to see what happens but he had a feeling what problem likely was but A&E protocol required taking baby steps before going to major repair. Rep was right - first moisture, then ice build-up in same area. Rep back for service call #2 on July 28. Service call #3 on August 25, service call #4 on Sept 6 but was not A&E. They quickly advised they could not work on units with R600 refrigerant as they do not possess the expensive/magic tool required to work on the same. A&E back for service call #5 on Sept 23 during which the rep with the magic tool replaced the coils and others parts. Unit worked for a few weeks unit High Temp warning light began flashing. A&E back to house for service call # 6 on October 6 by local rep who does not possess the magic tool and he advised they will have to start over with replacing the coils. Service call #7 was scheduled for Nov 21 but after waiting at house from 8-5, at 4:50, receive automated appointment notice with service call being rescheduled for Nov 23 (which I knew would not happen as the rep with the magic tool only comes to Granbury on Mon and Fri). Then, since we had not been waiting long enough for refrigerator repair, we were bumped down in A&E's service order to Dec 9. And, just to be sure they have enough parts to repair our unit, A&E has sent 3 sets of coils and other items to "fix" the unit. Needless to say, I have zero confidence that A&E can fix our unit and zero confidence the rep with the magic tool will actually show up for rescheduled service call # 7 on Dec 9.
