Best audio visual equipment rental service in Tysons, Virginia (VA) 2024

We held a big march in DC. On Thursday, our co-organizer spoke at length to the stores and reserved 4 megaphones. The store would not take the card over the phone. The next day, when we arrived in DC, the person we spoke to was extremely rude and sent a rude email as well and said she had all the info but we did not put the last 4 numbers of our credit card on the form. We asked for a couple of hours to go back to hotel to a fax machine. We sent in the information as requested. She gleefully informed us the megaphones had already been rented to someone else. Left us the day before having to scour the greater DC area for our march. Worst customer service I have ever had. ~Amy
