Appliance Service Depot – Service Doctors

My landlord found these folks in the phone book.
The driver, AP, showed up on-​time on Day 1 though he had no uniform or name tag, an unidentified vehicle, a generic repair form, and no business card or any other identification on him; because my landlord hired him I let him in the house.
He spent less than 15 minutes looking at my dryer before announcing it was the heating element. I asked him how he knew it was that and not the fuse or something else and he stated I just know because of my years of experience. Not terribly useful or comforting information.
He then announced that he didn’t have the part and what time the next day would I like him to show. I requested sometime between 9am-​12pm. He stated that time wasn’t available, but he could do between 7−9am. I thought that was a bit early, but as I could be available I agreed.
On day 2 at 9am I still hadn’t heard from him and got no answer when I called his phone.
I then called the office and spoke with Ross. He stated that they never schedule anyone that early and that they didn’t know what AP had said but he was on a job in DC, an hour away, that morning and that he was scheduled to be at my place between 9am-​12pm. Frustrating to say the least.
I then called AP again and got him on the phone, his response — I’m not scheduled to be there this morning, they must have given the job to someone else. I explained that I’d just spoken to the office and he was indeed scheduled to be here between 9am-​12pm, he then stated he’d be there.
At 11:50am when I hadn’t heard anything I called his phone again and got no answer; I then called the office again.
This time I spoke to Miranda who stated that the job in DC was going long and that they thought he was going to call me, and that she’d called him and he thought they were going to call me so it was all just a big mix up and that she was sorry.
I then requested that they give me a discount off the labor because of all the issues. She placed me on hold and spoke with James, the Manager, and came back and said that they don’t give any discounts ever because their price was already so low. I asked to speak to James and was told he wasn’t in the office and they wouldn’t give me his number. I was quite upset but as I hadn’t hired them agreed that the service should still happen.
At 12:10pm I got a call from Ross saying the technician was on his way. At 1pm AP showed.
It took him just under an hour to replace the heating element and the temperature gauge — and he had to call someone to have them walk him through the repair over the phone.
He stated afterwards that the office was just a call center who knows nothing about what they do, all the drivers are independent. He also stated that up until 6 mos ago he’d been working for an airline… so while his technical skills are probably exemplary — his knowledge of appliances, not so much.
