Anyone rent to travelling salesman. Scam?

[Paul Sandhu]

Had a call last Friday.  A lady affiliated with DirecTV wanted to rent a house for herself and 8 other salesman for 2 weeks.  They were going to do door-to-door sales in this area.  She wanted to pay with a credit card on Friday, and start renting the place Monday.  I told her to pay when you get here. Monday came and they never showed up.  Didn't respond to a text message either.  Now it's Tuesday and still no contact from them.  I called DirecTV, and they said any door-to-door sales would be a 3rd party.  

So I think it was some sort of scam.  I think she wanted to make a payment, but would want a refund a day or two later.  Something tells me I would have been out the money.  

What do you think?

She had reserved a 3 story house with 8 beds and 4 baths for $1200/week for 9 people.  I don't think she could have found a better deal anywhere else in this county.
