The worst ever five star hotel in Dubai with worst...

The worst ever five star hotel in Dubai with worst front desk staff. I had booking for my guests during the check in the reception staff ask the guest for additional payments for extra bed and breakfast though the booking was made for 4 adult and two child with one extra bed abd breakfast.
It was 1AM midnight the guest was keep calling me that they are asking for payment and 1AM i have to go to hotel myself to resolve the issue.
When i reached there one of the concern person at the front desk says that we just checked and indeed it was mentioned in the email.
It is such a shame that the front desk staff directly ask for additional payments instead of contacting the concern person who made the reservation.
On 12th August my guest need some assistance i call to the hotel around 7:40PM and a guy pick the call didn't transfer the call and he hang up. I keep calling no one picking the call or either the same person pick the call and then hang up without sharing his name.
I will take the same complaint to TripAdvisor and other places as well.
Not recommended at all better to go for 4 star option if you are not finding any other five star hotel but avoid park regis kris kin worst ever service.
