Complaint Review: Peter's plumbing

We got a quote to replace the pipes under the sink and take out garbage disposal for $250 and to change the flowmaster in toilet for $75.  I thought that was a good price.  After Andy the plumber at Peter's Plumbling completed the work,  he changed it to $350 for the sink.  He first quoted $250, then changed it to $250 - $350.

The overcharge was paid and they leave. Two days later, we notice a drip the bathroom faucet.  There were pliers marks on the faucet and a filter screen that was intentionally removed from it was left on the counter. No other way to say it. The same filter we fixed the drip with ourselves. Lessons learned:  Get a quote first in writing before only work is done, watch what they are doing at all times.
