Customer service is bad !! Called for one mechanic. Should be between 8 and 6 (nice time indication) I stayed home and asked for a day off! No one shows up all day, no call, nothing! When I called again I had canceled the appointment according to them .... my 3 month old dishwasher still broken. With the warranty they wipe their ass. NEVER MORE WHIRPOOL!
