a&o Frankfurt Ostend

I had been staying at this hotel for 6 consecutive days. The night before, I extended my stay for room 417 at the front desk. The hotel system has a complete record of my extension, and it was agreed that I would continue to stay in the original room. When I returned after going out, the hotel, without my consent or prior notice, unilaterally changed my room and altered the accommodation agreement. The new room had no duvet and no bath towels. I had to go downstairs repeatedly to request all basic amenities. One male front desk staff member was extremely rude and demanded an additional 1.90 Euros for a bath towel, even writing a note that said 'It cost 1.90 Euro.' I have uploaded a photo of this note as evidence. It wasn't until this staff member's shift ended that another staff member provided a bath towel free of charge. As an elderly traveler who doesn't speak any foreign languages, I had to rely entirely on a translation device for communication, which made interactions extremely difficult. Throughout my stay, I distinctly felt discriminated against due to the language barrier, leading to a terrible experience and leaving me feeling deeply wronged. I didn't get a chance to take photos of the missing items in the room due to the rushed circumstances, but all the guests staying in the same room that day can corroborate my account. I am attaching a formal complaint document in both German and English, demanding a formal explanation and apology from the hotel regarding the unauthorized room change, the staff member's improper charging, and the poor service, as well as reasonable compensation. The hotel system can retrieve the extension record directly, so I don't need to provide any receipts. While I don't have photos of the room lacking bedding and towels, there are other guests who stayed with me who can testify to this.
