"No match" does not mean unlicensed. Company names and phone numbers on a state list often differ from the ones in ads. Ask the company for its license number.
Before you call. Ask for the total price and which fees can be added: digging up or opening the lid, extra sludge, a trip charge. Ask if they pump every compartment through the main lid and check the baffles. Ask for the license or permit number. If the pumper says you need a repair, get three written quotes before you agree.
