Noisy & Can't get service satisfaction

Makes noises like plane taking off, animals groaning and people talking. Technician has serviced the unit five times and recommended replacement twice. GE refuses to replace, keeps insisting it is repairable. I've had the unit for four miserable months and cannot get any customer satisfaction. They keep stringing me along with one failed repair after another. This is the second failed GE product I purchased this year. The other was a water heater that failed out-of-the-box and took five days without a water heater to get it repaired. Will never buy another GE product.
