Worst customer experience

I have had the worst customer experience at Bagamoya Wildlife Estate. I wanted to use their venue for my wedding, but so far the way i have been treated is truly appalling. First, I wanted to view the venue, the contact person is rude and on many occasions ignored my requests and messages. I have had to send several requests until i got a response and was finally able to view the venue. I really liked the venue and decided on it for my wedding. I together with my planner thereafter started communicating with he contact person, it took almost a month to get a quotation and we had to alter between me, my planner and my fiancé due to poor communication from them. I understand there were some issues getting the quote but not even on one occasion did they make effort to get back to us on the delay, or in the least apologise. When I called the contact person blatantly told me that he had other things to do and did not have time to get back to me and explain the reason for the delay in getting the quote. Finally, we received the quote with a one-liner stating the amount for the venue; the amount was almost 3 times what was put up on the website. I therefore, asked my fiancé to call and find out the detail of the quotes and see what we could do without and also to get a cost breakdown as per normal quotes. He was told that it is standard. We called again to find out if the date was still available since we were told other people were also interested in this date, and to find out how we secure the venue. The contact person told us that we need to pat 50 % deposit and within the same month pay the full amount. I have never heard of something like that before. It almost feels as if they trying all their best to keep us away from booking this venue. My real question though is whether this is how all the clients are treated? I have never in my life felt like my clientele was worthless than this experience.
