John Chambers is not honorable person , he is one man show and never finish work. He agreed to do a job for us and he got couple of service call so put our job aside , he even told us he got couple of service calls after our job and he also think (not sure) there is a bigger job is coming his way so he can't do our work, he wasted our time for half a day to show him different jobs and he simply don't follow thru. DO NOT TRUST THIS GUY TO FINISH THE JOB, DO NOT GIVE HIM ANY UPFRONT MONEY AND IF YOU CAN AVOID DEALING WITH HIM GO TO ANOTHER CONTRACTOR HE ONLY WILL WASTE YOUR TIME. THIS GUY IS NOT PROFESSIONAL.
