Embarrased and annoyed

I booked one night to book in 28th and book out 29th January through the MVG. To stay at the carnival casino, the lady on the phone asked me for my MVG account no ,which I gave her she ,she ssid she c as n offer me a room at a very good price at R676 without breakfast , I asked to book as it was my 26th wedding ann8versary on the 29th , but could sleep over o. The 29th due to work commitments on the 30th ..she gave me a reservation no ***4, ,Her name was Precious .. I phoned last week to confirm my booking and was told everything was find ,To my surprise arriving today atc2pm at the hotel a lady not sure if I have the name spelt correct Tsolofiswa at the reception at hotel said room is booked and I must Pay over R2000 rand, I told her that is incorrect and she checked my b.c reservation and then phoned MVG desk where they said nothing can be done until we speak to Precious as she made the booking, and she did the error as the special ..as l was only for gold card member and my card us a silver ,no sympathy sat with her arms folded like nothing I can do .. so I left my bags there and headed dor the MVG desk on the casino floor spoke to one if the ladies their which then got on the phone for like ten minutes chatting , I asked her what's going on said they talking to the bosses eventually she said Precious who made the booking wants to speak to me on the phone. AT this point I'm feeling so embarresed as this was suppose to be a gift to my hubby.Precious started attacking me on the phone ., saying I asked you if you has a gold card ,I calmly corrected her no you didnt , I asked can I make a booking for these days you checked availability and then asked for my card no you then told me the price and gave the reservation no. No is it my fault if they didn't check on the system..I'm just wondering what will happen I'm coming from all the way from the westrand what if I came from Durban etc...she said I can't chante your card to Hold , I said yes I'm not asking you but you made the error, she admitted, but said they cant help, now bare in mind , I have a suitcase packed for a overnight with hubby to celebrate our anniversary . I am very upset,angry ..as and embarrassed about this..I had to po hone the road lodge and book into there ..very upset even getting chest pains ..just no empathy, the service was terrible and then to be attracted ..attacked on the phone like it was my fault..very annoyed and embarrassed.
