bad service

I purchased a dish washer from Sears about 2 years ago With a protection agreement.They have been out 4 times in the last 3 months to try to fix it and I still don't have a working dishwasher.I was told when the serviceman came out next that it would be my 4 services and I would get a new dishwasher but when I he came out they told him that wasn't true even though I talked to 2 employees that told me I was and 1 of them was a supervisor.I called sears again to talk to someone and first got someone in the Philippines when I told them I wanted a supervisor they gave me a number to someone in the USA I talked to another guy for a while and asked to talk to a supervisor who explained how I did have 4 services but the one was a month to late even though they have been trying to fix my dishwasher for 3 months He then said He would see what he could do and call me back which He never did what service.I will never get a service agreement from SEARS again and I will never buy another product from them I can see why there going out of business they don't take care of there customers anymore
