We found out that priceline charged more than the hotel did and called the customer service to cancel the reservation.
The customer service was very rude and they called the hotel to adjust the price up.
Surprisingly, the big company like Priceline does not have the complain number and no google review,Which is the reason why they do what ever they want.
I feel so shame about it and advise the people do not use it anymore.
It is a dark company and avoid at all cost.
You have no place to tell the truth.The customer service's employee id is 5260313 and she makes me feel I was ripped off with not choice
