Western Union — debit card usage

Address: 31820

My name is patrick, i used the online western union to transfer money to haiti. It allowed me to make two transactions using my debit card and when i tried to use it again to send money to another person, t it will not allowed me to use it a third time. The reason that i used the online is because it is convenient and i don't have to drive 30 minutes. I understand the security but there are ways you can check if someone is a fake.
I support 3 to 5 people that i send money to in haiti. The system that you have now will not allow me to do so. I have to go to a store completely out of my way to do so. It will help if they can modify the system to make it friendlier.
