I needed to rent a helium tank for a party to blow up 100 balloons and have called around asking for price. Balloon Celebrations gave a competitive price and was closeby to where I lived so I made a reservation to pick up a rental tank. I paid for enough helium to blow up 100 balloons, yet, I was running out of gas by the 40th balloon. The balloons blew up extremely slowly after that and I did not even get close to my 100 balloon expectation. I left a message since they were closed for the day, but nobody ever returned my call. I returned the tank the next day and got nothing resolved.
