Step by Step Remodeling

I paid for a siding job on the outside of my house upfront in cash and never received any invoice or receipt for the partial job that was done. The siding outside is crooked and water is seeping into the house and the interior was never completed. I have called him multiple times and left various messages but no returned phone calls. It is very unprofessional behavior and unacceptable. I would be very careful selecting them for service.
