Wednesday day, I went to help a customer with an media air cleaner problem. The customer called us because the media air cleaner was not laboring properly. The media air cleaner repair was the first task on the schedule for me. I left the workshop and proceeded to the address. The customer was apartment and I arrived a few hours ahead of schedule. The man answered the door and talked to me briefly about the media air cleaner. I started laboring on the issue. The repair did not take easily long, because the issue was minor. The media air cleaner has a small air filter inside of the machine. The air filter was obstructed. This was the reason why the media air cleaner was not laboring. I cleaned the air filter and took care of the machine. The entire task only took about an hour. When I presented the customer with a bill for $172, he started yelling and screaming. The man told me that I was only in the house for an hour. She wanted to guess why the bill was so high. I told the man that the two of us charge a flat repair fee of $119. There was a charge on the bill for parts and taxes. I tried to explain all of the fees, but the man wasn’t listening. She kept yelling about the charge. I did not feel he was going to pay the bill, however he finally offered in and wrote me a check. When I came to labor the next day, my boss told me that the customer called to complain about the bill. I feel he wasn’t done complaining about the charge.
