Worst customer service ever.
I requested an invoice or receipt when I checked in, the first gentleman on the reception told me he would give it to me when I check out.
When I requested it again when I checked out, they deny to give it to me because I paid to hotels.com. when I requested them to the manager, he told me he would send to my email in 2 days.
When I call him 4 days later, the manager asked me to call his senior.
When I called the senior manager, he promised me to give it to me, but he also didn't give it to me.
All 3 people at the hotel didn't keep his word.
Also, the breakfast was not very good.
I think the most important thing in the hotel is try to satisfy customers. I guess they don't want be bothered to take 3 minutes to print an invoice or receipt because customer satisfaction is not important.
