Outsurance has horrible service providers with sub par equipment and service

A while ago my dishwasher got damaged due to some power surges. Outsurance then approved the claim and a 3rd party service provider delivered a Samsung dishwasher. Just over a week ago the control panel of the dishwasher gave in. The dishwasher is still under guarantee. So I phoned Outsurance and they referred me to the 3rd party service provider. I called them and spoke to Gregg, he was full of stories and after a dozen calls and a lot of arguing, he said a service repair team will come to fix the dish washer. For over a week nobody pitched and every time Gregg was full f stories and even became irritated and rude. I called Samsung and they did not even know anything about this repair. So Outsurance really need to check their service providers as they are giving Outsurance a bad name and reputation. This is very frustrating as I have small children and work 6 days a week and rely on the dish washer to keep my house clean. How long do I still have to wait for it to be fixed....?
