We had a service call to diagnose a toilet problem. Brayan and Eduardo came. They were both as nice as can be and knowledgeable. In the end, they replaced the fill valve. The charge was $500. After they left, I went online and saw that it's a $25 part. While I respect the service plumbers offer and understand the cost of doing business, I feel that being charged $500 is exorbitant and out of whack. I called after and spoke to a supervisor to try and get a better understanding of the markup. He wasn't helpful, didn't offer a credit for future service or anything else for that matter. We will not be using them again.
