Not his fault there was nothing wrong. He still showed up and did his job, so the charge is valid.
My internet connection was down more than it was up so I called for assistance (the connection was flip flopping between Network 5 and Network 6). The tech I was talking to ran his tests and concluded that there was a problem with the dish communicating with my modem and a tech would need to come to the house to fix it. He said there was normally a $125 charge for this but that charge would be waived and I would recieve a credit for the down time. He said that a technician was scheduled for Tuesday the 19th. No-one showed up until the 22nd. At that time the service was up and connected without a problem (for whatever reason), so there was nothing to troubleshoot. The tech tightened up a bolt on the roof mount but otherwise just looked at his handheld device. I asked if maybe it needed to be realigned, and he said no. He was here about 10 minutes and left (with me a bit disappointed because nothing was actually found wrong). Now I've been billed the $125 anyway - it's already been taken out of my bank account. I think I should get a refund
