Best Leach Field in Raleigh NC

We called Roto Rooter to come to unclog a floor drain in our business. I asked when I called what the price was for the service call and was told that they didn't know how much until the service tech arrived. I had already searched other agencies and knew it was about $200-$225 for a drain snaking. The tech quoted me $500 to do the work which was double what others were charging. Since the tech was not on time, there was not enough time to call anyone else. The tech also told me that he was hitting something hard in the line and had to really work it the line to get it free. I asked if he had broken anything while forcing the snake and he said he wasn't sure but he could get the camera tech to come and look. I said I wasn't interested to pay another fee, which he said was free, then said the tech couldn't get past the pea trap with the camera.I feel like I was overcharge and Roto Rooter could have given me an idea on the phone instead of holding me over a barrel to get this service done at the last minute.
