I scheduled Preventive Maintenance appointments for 8/24/21, 8/26/21, 8/31/21, 9/7/21 and no one showed for any. I contacted Sears many times and was told someone would get back to me to let me know why no one showed up. I did not receive any calls from Sears. Several times I was transferred to another number/person who answered and put me on hold and never came back on the line. A couple of times I held for 30 and 40 minutes.
