Payment doubling from bills

Customer goes to pay the bill and it doesn't work, then they pay again and it double bills them.

Reproduction Steps:

1. Receive bill

2. Click to pay bill

3. Bill stays on app

4. Click to pay bill again

5. Bill pays

6. Look at bank account, double, sometimes triple amount comes out of account.

Expected: Pay once and it is removed from your bills and only takes one amount out of account.

Actual Behavior: Takes amount out of your account as many times as you click pay bill

This seems like a connection issue. We've had it happen at Soochi's from three different people recently.
