Riverbend Appliance - Calgary

About 3 weeks ago we had issues with our dryer. We called Riverbend appliance and they sent someone over in just a couple days. Upon his first visit he told us it was the heater (which is the most expensive part to fix) and a pulley system. We got him to fix it and 3 days later our dryer was making the same sound. We called back and the same guy came back again. This time he told us it was the motor and venting system. Not wanting to pay money for another part that may not be the problem we asked what happens if it still doesn't fix it (he said he could refund us the heater part, but would have to take it with him and not be able to replace it with our old part, leaving us with a broken dryer). He could not directly answer our question, and said a Manager would be in contact shortly. We didn't hear from anyone so we hired a different company. This guy told us there was no way it could be the heater and it was the pulley system the guy first talked about, but he had not installed it properly or greased any of the parts. This other company fixed it no problem and we have had no issues since. We finally got in contact with a manager from Riverbend appliance (although we had to call) who said they would refund us what the other company did as soon as we sent him an invoice. That as a week ago, and we have not heard back. Everytime we call Riverbend appliance to talk to someone all they can say is they will put in a request for them to call us and we never hear back. I would NOT use this company. UPDATE: Manager called us a week to later to say he did not get our invoice to refund us. Sent it again (multiple times and through text) and once again have been met with silence in return.
