@Impark I submitted my receipt but no reply. Then I received a letter asking for payment. I submitted all the proof again, no reply. Now I was sent to the collection, without any reply.
@Impark I parked in one of your parking lot in Vancouver since I had a performance around there at 7:00pm. I paid on Hang Tag at 6:58 and received the receipt email immediately, so I left and run to the performance. Later I received a ticket saying that the payment is not succeed.
