Sears review: Front load washer/dryer combo repair service resulting in water leakage into my crawl space

My LG frontload washer (stackable) was making a banging sound, the technician (Joseph) came out on 10/30/2023, identified the problem, ordered parts, rescheduled me for 11/16/2023.

Hunter came out on 11/16/2023, replaced the parts, except the gasket. He failed to look through the parts packaging which he admitted to, so assumed that the gasket wasn't ordered. He assumed everything was fine by running a cycle, told me I was good to go.

I did a load of wash and had water all over my floor, leaking down into my crawl space, now concerned about mold.

Hunter came back on 11/18/2023 due to the water leaking, found the problem, admitted he hadn't looked through the packaging. I showed him the 4 parts I found after he left, one being the gasket he missed the first time but he didn't have any help to take down the dryer so had to rescheduled me for 11/29/2023, even though he knew I had a stackable and didn't bring anyone with him. He could have fixed it the same day.

There are also 3 other parts that were ordered but not needed and I need to be reimbursed for the cost of those parts. He also told me he needed to order another gasket in order to create an appointment for me, so the cost of that part will need to be removed from my account.

I want Sears Homes Services to have someone come look at my leakage in my crawlspace to determine the damage and repair or have a contractor

repair and pay for their charges as quickly as possible.
