General Electric / poor quality and microwave error codes

Contact information:

I have several GE applicances which came with the park model I purchased brand new three years ago. Since then the side-by-side refrigerator needed service for the computer and now the piece behind the water dispenser is all cracked. Recently, the Space Maker microwave has started reading error codes. I cannot find an email address or a phone number to express my disappointment in these products. Again, t he products are only three years old. I always thought GE was a dependable name, obviously I was mistaken. Please provide me with a phone number, email address or mailing address where I can express my concerns. Gail LaFlamme
