The worst customer service

The sears tech came out to perform annual maintenance on my heat pump (bought in 2005). It worked fine before he got to my home and fine while he was there. As the day wore on and the July temps were climbing we realized the house wasn't cooling off. Of course, this was on a Saturday and they wouldn't send him back to the house. The best I could do was a Wednesday appointment sometime between 8 and 5. The customer service department wouldn't return my messages and the contact center wouldn't put me through to anyone else who could help. 2 days later, I found this weird shaped piece of metal in the grass. Turns out the tech forgot to put the breaker back in the outside box after service. I stopped payment on my check to them and now Sears has sent me to a collection agency to get my $89 for crappy service in my home and crappy customer service. I HATE SEARS AND WILL NEVER SPEND ANOTHER DIME WITH THEM!
