Frigidaire GLET1031FS Top Load Stacked Washer / Dryer

Since the unit has turned 1 year old I have had non-stop issues with it. Service has been to my home on 3 seperate occasions, and are now coming out for a 4th time in the last 60 days. All because of the DRYER! First time a bolt fell out (tech. told me to replace it myself if it fell out again), second time the dryer was running loud only to find out it was missing a dryer seal (the felt ring that stops metal from rubbing on metal when it tumbles) this part should have been installed in the factory!!! They had to order the part, replace it and now service is coming out a 4th time because it sounds like I have a basketball tumbling in the dryer! I am sick of this dryer and all I want is a refund and I am going to buy another brand!
