Appliance Repairman

Our LG dishwasher started leaking after 5 years of solid use. We called Appliance repair guys because other companies said they don't deal with LG machines.
A technician named Matthew spent an hour reviewing our machine and said he would need to order some parts and that may take a while. Weeks went by, more weeks. We called the company each week and they gave us the run around, never providing us with any actual information. Which part? What is the timeline? Finally, after escalating to the manager they informed us the repair would be over $600, about twice what we were expecting. In the end I am going to buy a new dishwasher because spending $300 (labour) + $600 ( repairs) + taxes does not make sense on a 5+ year old system. It has taken 8-9 weeks to arrive at this outcome, no help from Appliance Repair Guys. They claim they will refund us $100. We'll see about that...
