This is an unethical company.  They are illegally going door to door passing out free gas drawing cards.  This is and independent Kirby Vacuum company getting your name/number to solicit.  They are good at giving out cards saying they are not selling anything but ultimately they are soliciting.  They also say they are giving free demonstrations and will clean your carpet.  Gas drawings and free demonstrations is their sales plan.  It IS soliciting.  They are gathering info to solicit you.  Their round about way of doing it and claiming they are not soliciting or selling anything is wrong.  They are soliciting and need to comply with all local codes and ordinances regarding door to door sales.  Make sure they have a permit from City Hall.   Always ask to see the permit.  It is usually each "person" that is permitted and not each "company".  The gas card says PROAGO, INC. 5200 NW 2nd Avenue, Des Moines, IA  50313.  This company is no longer registered with the Iowa Secretary of State office.  They were revoked for failure to file required reports.  Kirby warranted units are only sold by independent sales reps so, just like any other independent sales reps, they will use any means to get a sale whether it is illegal or unethical.
