"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."
