Sears review: $525.06 charge to my mastercard on 7/29/23 for an icemaker

Initial service visit on 7/29 erroneously diagnosed faulty ice maker in my Kenmore Service Tech (Matthew) ordered new ice maker & $525.06 charged to my MC. 8-7 visit by tech but parts not arrived, 8/9 tech installed new ice maker, 8/12 as ice still not made ice Matthew confirmed his diagnosis was in error, there was nothing wrong with the original ice maker. Matthew now diagnosed that an additional $1,200 to make the ice maker work, even though all other compartments of the Kenmore worked fine. He said I would receive full credit for $525.06. After many hours calling several #'s on 8/14 I was told my claim was being processed. On 9/8/23 I received an e-mail from Sears Home Service Email Team stating that the PARTS WERE INSTALLED & CHECK OPS OK. As Ice maker still did not make ice, I got rid of the Kenmore and purchased a new refrigerator. I have called more than a dozen SEARS #'s and can't reach a person.
