I signed up online with a promise by the website of three hours for delivery and installation of a battery for a 2017 Jeep Grand Cherokee Summit. That was at 1:30 PM on 12/5/22. At 5:30 PM on 12/5/22 I called customer service because the delivery did not happen. The service agent told me that the assigned technician was out sick and would not deliver the battery that day. I agreed to a 10 AM delivery on 12/6/22. At 11:00 AM on 12/6/22 I called customer service yet again to report that the tech had not yet arrived. The agent told me that the tech was in the field and had my name on his customer list. Sherman Williams arrived at my house at 1:45 PM. Oh, BTW the first customer service agent said I would receive a discount from the agreed upon price. No evidence of a discount has been received.
