We didn’t know we needed a voucher for car pickup. Two days ago, another staff member just asked us to take a screenshot and email it to them. But this staff member didn't allow that. Since this app logs in with a phone number and requires a verification code, we couldn't get the code. Even when we showed the long saved screenshot of the voucher, he said it was too small to read and made exaggerated gestures. He complained that we didn't print the voucher last time and still didn’t this time! We arrived at 3 PM and dealt with this until 4 PM without success. We had to rush back to school to submit documents and ended up taking a taxi. When we told him we would take a taxi and come back, he rudely replied, “What difference will that make?” His attitude was terrible. We asked a teacher to help print the voucher and took a taxi back, and he still claimed it wasn’t the correct form, with an awful expression on his face. Ultimately, he reluctantly said it was okay. My friend and I were very upset about the wasted time, the poor attitude, and lack of clear instructions. Even after we printed all the clear and readable information, he insisted it had to look like previous customers’ vouchers.
