I ordered a Lennox 23L53 Control Board from this site on October 23,2011, but they have never shipped the part. I have left several email messages with them and tried to contact them by telephone with no answer. I have emailed them again requesting a refund. I believe this is a fraudulent operation. Do not, I repeat: DO NOT do business with them! I am going to turn this over to police and/or Better Business Bureau.
