Service 4 Appliances

Called this company to repair my dishwasher. The repair man charged me $240 to take it apart, and then told me it was not covered under warranty, new part would be $600 + labour and it was not worth repairing. I called Bosch directly- was told the part is only $150, and is covered under warranty. I contacted service4appliance to let them know the discrepancy and they never addressed the issue or followed up with me.
