Blindsgalore.com Room Darkening Blinds Too Small - Suggested I tape the edges to block out sun!!! Internet, Internet

Shameless plug, wouldn't you say? 

    I think this company may have been better off not responding at all.    The response does not address the OP's issue, it sounds more like an advertisement.  You'll note that they didn't bother to directly address the OP's problem at all.  I wonder if they hire out of work robots to respond to their complaints.
