Darren: Have you all paid for the entrance?
Paula: Yes
Jim: I did, but I haven’t received any confirmation from the organisers
Darren: Hm, that’s weird, you should have received an email after your money went through
Jim: Check your account history
Paula: It says that it went through
Darren: Weird… I don’t know what must have happened. Maybe the system’s failure
Paula: I will contact the organisers, I hope they will let me in
Jim: Maybe print out the bank receipt just in case to prove you paid
Darren: Good idea, they may not have enough time to respond
Paula and Jim have paid for the entrance but didn't receive confirmations. They will print out their bank receipts.
