Best Mold Inspection in Washington DC

I got sewer line blockage last night. Drainage backed up in the bathroom of the basement. First home buyer, no experience, no idea what to do. Called my agent for help and she recommended roto-rooter. Called them and waited for 1 hr. The two gentlemen came and fixed the sewer line blockage caused by the tree root. They were doing the service in a professional way. However they asked me for $1,200. Called my agent and she was astonished to hear the bill. For her case of emergency blockage using roto she only paid $600 for much worse cases than ours. Even the customer service manager was claiming that they charge $599 for the standard blockage.This bill is unreasonable and overcharged way too much. After contacting the customer service they agreed the charge is too high. And they are willing to refund the overcharge amount.
