Very unhappy customer.

I have a problem with The Peach Tree Restaurant at the Cullinan Hotel. I was told to phone and find out if the restaurant was fully booked on Sunday morning by a very helpful Hilda but the Restaurant Manager Shamsonesa was not very abbliging. When I phoned she informed me that they had a booking of 100 persons and could not accommodate me but on numerous occasions when we were told they were fully booked there was a number of tables open. When I informed her of going there and finding this out she tells me the restaurant will not give me a table just for 4 people with an attitude.
