How to get our money back from the airline company?

HI On 08/09/2022 we visited the airline company office in Breda. We bought a holiday package for 3 people to Bodrum, Turkey. 5 star hotel all inclusive. I only have a Hungarian identity card. My partner and our son only have Polish ID's. Our first question to the employee was whether we can travel to Turkey only with ID's since we don't have passports. His answer was "yes, of course they can." He asked for their IDs, checked them. He entered the data. We didn't see his monitor to see exactly what he was doing, so we thought he was looking into it. Of course, we asked again if we can definitely travel with our people to Turkey, the answer is still "Of course you don't have to worry". So we bought a holiday package for 3000 euro's. We were really looking forward to the whole thing, especially my partner, as she never been on a similar vacation in her life. We went from Breda to Amsterdam at dawn on 09.25.2022 (Sunday) to the airport and there they didn't let us on the plane because we needed a passport for Turkey. The airline company gave us the wrong information and it was missleading we don't need a passport. We had to go home by taxi completely devastated. The next Monday morning I immediately went to the office to see what we could do. Either refund the money or exchange it for another trip where you don't need a passport. At first, the employee said that the money can't be returned, but they'll see what other vacation it can be exchanged for, but he said that he's busy now, so he'll call me later and inform me. He called me and said that neither money will be returned not that they are willing to refund 10% of the entire amount for another non-exchangeable vacation. I think that if the airline company provided the wrong information, it should take full responsibility and if not refund the amount for at least another vacation to switch.
We received an email from them I will copy it below.
"Dear sir, Thank you for your feedback. We are very sorry to hear that you had this unpleasant experience regarding your canceled trip. My apologies for the inconvenience experienced. We have been in contact with the travel agency where you have booked. They informed us that it has been indicated that your son could travel on a Dutch ID card, because you indicated that he was born in the Netherlands. My colleague, with whom you booked, indicates that there has never been a conversation about Polish and Hungarian ID cards. The responsibility for being in possession of the correct travel documents also always remains the responsibility of you as a customer. Because we find the situation very annoying for you, it has been decided that we will pay out half of your travel sum as a courtesy in the form of traveler vouchers with a validity of three years. I would like to receive your name, address, place of residence and zip code for verification. In addition, you are also entitled to a refund of an amount of € 386.25. Refunds are made via website. You log in with your reservation number, surname, and departure date and only fill your bank account. After receiving your details, the amount will be on your account within 14 days."
We are not agree with this solution. We'd like to ask for a professional view on our next respond/email to the company. Can we send you the next email what we want to send to the company, and there is any advice what you can give us?
