Wisma Mutiara Syariah Langsa

I booked one room online at Trip.com and used my credit card to pay for it. Everything went well during the booking. But the disaster started at the time we checked in. The receptionist could not find our reservation despite the confirmation number and the pin that I presented during the check in. Nevertheless, a male receptionist gave us the key and assigned us a room. At around 10am , before the time of check out, I was a the lobby and a female receptionist called me and asked me to pay for the room. I told her I made a reservation via Trip.com and already paid the room online. Despite all the documents about the reservation and the payment receipt, the receptionist insisted me to pay for the room, because they had not received any confirmation or payment from Trip.com. I paid Rp200.000, (two hundred thousand Rupiah), the amount she was asking and I asked her to give the receipt. she issued me the receipt. She told me that the hotel has no business affiliation with Trip.com. The hotel accepts reservations only from Expedia.com, Traveloka and others but not Trip.com. Because of that, my reservation and payment through Trip.com was not honored. I checked my credit card account, and I found that there is a charge from Trip.com. So, what is the charge for?? Is sit FRAUD? At the time I am writing this comments, I have not received the response from the hotel about the proofs of my reservation and payments. Trip.com sent me an email that promised to follow up with my report and complain. Let's see if I can get my money back. I did what I did, because I was not there to argue or fight with anyone.
