Myers Plumbing

They were supposed to install instant water heater and softener I bought ahead Estimate was 600. After they installed softener I paid 500 expecting I owed only 100 more and parts Final bill was over 1100 more and included a new sump pump. While installing heater and new circuit breakers they unhooked wire at box to furnace. This was in Sept. I was unable to start furnace but finally got furnace expert .Van horn yesterday Oct 15 who discovered wire disconnected. That was another 75. Last plumbers at house 2 years ago fixed a leak by cutting pipes to electric tank and I found they had disconnected plumbing to half bath. Did not get that fixed yet. Oh Myers head guy sat in his truck and let young man do work and only went in to check . yet I had to pay for his time sitting in truck apparently. Is this the way world does business now?
