Business ProfileforRoll Up Doors Direct

Hello. Thanks for your help. I ordered a product from Roll Up Doors Direct but did not receive what I ordered. They have been in communication with me, and acknowledge the error, but blame the subcontract manufacturer ***** ************* and suggest I contact them. As I have no contract with Janus, I feel Roll Up Doors has to resolve this. See attached pdf for receipt details and communication chain. I ordered the most secure locking mechanism, the cylinder lock which engages on both sides, for an upcharge of $45. It should have been installed on the product by the manufacturer. Once we got it home, unpacked, and my contractor got it up, I realized I received an exterior latch which only engages on one side. This is the standard offering and not as secure. Roll Up doors offered me two options: 1) keep the external latch that you received and get a credit back for the cylinder latch, or 2) you can punch the hole yourself into the door for the cylinder latch and we can ask for them to give a credit for the mistake made during production I explained that with a field install I would be taking all the risk if the install was incorrect. I paid for a factory install and do not feel a field install by homeowner is equivalent. I asked them to resolve this by either A) coordinate hiring of a garage door installer to do the field install of the keyed cylinder lock, and guarantee the installation work just like they would stand behind any problems with a factory installed lock. B) I will just keep the door as-is if they give me refund of the $45 lock plus 20% off the price of the door. They refuse to pay for professional install and say the error is with ***** *************. They refunded my $45 saying it is all that they can do. However I feel there needs to be additional financial compensation for the error. I feel 20% refund is fair to keep as-is, or they want to pick up this one and ship me another in, that is fine as well. I am hoping you can help resolve.
