I Booked Riserva Urla Hotel on Trip.com for the Holiday, But Hotel Denies My Reservation

I made a reservation for Riserva Urla Hotel through Trip.com for the holiday. However, when I called the hotel to confirm, they told me no such reservation exists under my name. The hotel staff were surprisingly calm about it and said this kind of issue is normal. I’m confused and frustrated because I don’t know what steps to take next. Has anyone else booked through Trip.com and successfully stayed at this hotel? This experience is very worrying, and I need a solution urgently. I hope Trip.com addresses this problem quickly so I can enjoy my holiday without further stress.
