Charge, Singapore Road trip Q&A

I just returned from Sweden in August, and I have had many appearances before, including developed countries such as Australia. In theory, there should be no problem at all. I am now worried that the Zhongzhi Visa Center is playing tricks. I was supposed to submit my documents on September 1st. At that time, the staff checked the child's documents first and said there was no ticket pre-order. The child's other documents were all qualified. I actually bought the ticket, but I was confused and didn't print it. I told her I would go to the lobby to print it and come back in ten minutes. She said that even if it was a supplementary document, all three people had to upgrade to VIP, and each person had to pay an additional 250 yuan. I thought it was not worth it and said I would come back another day. So I made another appointment on September 5th. I checked the documents at home many times and thought there should be no problem before I went. As a result, after the staff checked all our documents, they said the photo was not qualified, and the proportion of the face in the photo was too large. I said I took it when I applied for a Swedish visa in July, and most importantly, the staff who checked the documents a few days ago said that everything was fine except for the lack of a ticket pre-order, and they even asked me to paste the child's photo on the application form. Why did they say the photo was not acceptable this time? Isn't this finding fault for no reason? I was particularly angry at the time and argued with them. The staff asked for approval from their superiors, but they said that the result of today's review was final, which was simply unreasonable. Both my partner and I went to take photos again, but the child did not go. In the end, we had to go to the school to pick up the child and take photos, which was simply trying to find ways to charge extra fees, shameless to the extreme. I don't know if they have submitted our documents as required, because based on the situation of submitting documents twice, I think the conduct of the staff of the Zhongzhi Visa Center entrusted by the embassy is really not commendable ?
