Len the Plumber of Baltimore, MD - Harford County review: Overcharging of work and unnecessary work against a customer

The Len plumber technician Informed me I needed additional shutoff from the kitchen faucet because he did want to come back to the faucet leaking. I informed the customer I would be given a veteran discount I have called several times and Len's manager has not called back to discuss my issues since 13 Jul 2023. I know I was taken advantage of as a senior and a veteran. I can't locate the additional shutoff installed for ($415.00) near the kitchen faucet when the technician was with me nor did he try to show me the exact location. I do not need one because I already have two shutoff valves at the bottom of the kitchen cabinet for the hot and cold water which are connected to the main water shutoff. I was overcharged for a replacement of a kitchen faucet and an additional shutoff valve.
