Express Appliance Repair

I am very regret choosing this company. My ice maker didn't work after I changed the water filter.
The service call cost me $90. The technician named Roman took 45 min. to diagnose the ice maker and water valves, then told me the ice maker was broken, need to be changed. The cost will be $434 for part and $195 for labour. I thought the price of part was little pricy. So I found a Factory Certified Parts Distributor from internet. Their price for the original part is $185.
I trusted Roman beasuse he looks nice and he told me that he has doing this job for more than 10 years. So I planed to buy part myself and ask him to change for me. But the Parts Distributor told me part can't be refund, they suggest to make sure the ice maker broken. So I spent $192 call the factory certifed repair company to diagnose my ice maker. That technician took 15 min. found out the problem is new water filter doesn't match my fridge. Nothing but filter need to be change.
Technician is not qualify, but this is not the only problem of this company.
I call Expressrepair ask for the service call fee refund beacuse of the misdiagnose. I was asked to send the invioce of the other company's service. I sent to them and be told I will get refund after they look over the claim. After 3 days, nothing happened. I sent an email asked what is going on, no respond. After a week, I called and be told somebody will contact me the next day. 2 more days past, still nothing happened.
I know the customer care person will write the routine respond like them treat customers seriously, and let me call them to get a satisfactory solution. Don't belive it. If they really want treat customers seriously, they will contact customers instead of been contacted. I am regret did not check the Homestars reviews before I call this company.
