Hacked again? ...Is this spam?

I got an email from the Radisson Hotel... I kept turning it over in my head, thinking this way and that... Wondering "what is this?"... For two days I've had a headache worrying back and forth about this.

I did visit the Radisson Hotel in Da Nang.. and I think it was a room charge receipt. It's in Vietnamese... I can't figure it out at all... I need a translation...

What is it? What is it?

When I used a translation app — Why? A receipt? Did I go to the Radisson Hotel and get some kind of statement? It says to click to view the receipt...

What is this even about... =_=

Vietnam Post? What's the login username and password...

I clicked and it's a receipt? My name is on it, but... Looking closer, what's this usage record from August 25th? Room charge? I paid the room charge at the pool bar...

Is this the room charge from my last stay? Are they sending the old one with an issue date of August 25th? But why is the room number 9045? I've never even been to that room... If only we could communicate, I'd try calling the Radisson Hotel, but since I can't make the call.. But you know, I only just found out today.. Only just now... Oh no!!! T_T For the past couple of days, this one receipt kept nagging at me.. Why didn't I even think of that... I just assumed the date shown was the writing date, and wondered why the room number was wrong? I only suspected something... Why didn't I notice the strange address... T_T I did click on the receipt to look at it though... T_T
