Max Appliance Repair

I called for service on washer in my rented condo in Ottawa area. technician showed up too late while my tenant was waiting for him. technician told me he was sent by the office to the wrong address. I am a landlord living 8 hours away from Ottawa and based on reviews in Home Star I called Max Appliance Repair for this service. after diagnosis technician called me and said the cost of the repair will be 418.00 +tax and labor 220 +tax. I asked how I can be sure this will fix the problem? technician said if did not fix the issue, I will be refunded for what I paid for the parts but I have to pay the labor and he asked for cost of the parts as deposit. I said I pay the labor cost as deposit, if it worked then I pay for the parts, if it did not work you are paid for your labor already, I don't owe you and no refund. at this time he started to get upset and rude, he said the office should have got your credit card number before sending me here and he hung up on me.
then I received a call from the office telling me that I refused to pay for service call. I said, I have not refused to pay for service call and explained the situation. the office asked me to pay for service call. I accepted to pay and asked for the written report of diagnosis. they said you have to pay first. I paid and the report I received was less than one line, very unclear:
"Estimate for repair service: Parts 418.00+tax Labor 220.00 +tax"
as a landlord I expected to receive a reliable service and pay the bill with peace in mind but it was not the case and it was a very unpleasant experience.
