I've been having problems with my drier for almost 3 months. Each time a technician comes out it is up to me to decide what the problem is with my drier and what needs to be fixed. Now after being told that someone would be out yesterday February 20 I call to see what happened and was told that I have to wait another 2 weeks before someone would be out. I told the person handling the call that another 2 weeks is unacceptable especially after the 4-6 weeks I've already been waiting to have it fixed. I was told that there was nothing that they could do. This will not work because when the technician comes out and the problem is not fixed(because I have no clue about driers) I will then have to wait another week for the part and 2 weeks for an appointment? Is this now how Sears works?
