Service 4 Appliances

I called for servicing of my dishwasher as it would not drain; the service person said it needed cleaning only and said it didn't need anything else... approximately a week afterward it made strange noises but was working; it then ultimately started to again not drain. I called them again and they said no warranty and I would have to pay $50 for them to attend and
pay for the time or parts afterward. In my opinion it was not fixed properly and they are simply taking my money. Very bad service and will have it repaired by another.
