312-640-2545 is a Sears # in our case it was an automated survey to rate A & E Factory Service which we had when our washer broke down. A & E is owned by Sears, so if you had any repairs on an appliance or other items that is probably what it was for. The automated machine would diconnect if we did not pick it up immediately and the number comes across as "unknown name". Once you answer the survey the calls will cease as its simply a way to rate your customer experience.
Yes, from A&E factory service. I had spent hundreds on local business appliance repair, got smart and used A&E factory service. Great results, Just keeping an eye on their client satisfaction.
