NEVER SUPPORT THIS RESTAURANT!!!!

I made a group booking for 25 people for a kitchen tea more than a month prior to the intended date it was supposed to be held. I discussed the details with the owner and she ensured me everything will be 100%, I just need to pay for the food in advance. I received an invoice and paid the money. Approximately a week after paying the owner stopped responding to my emails. 2 days prior to my function I drove the restaurant to confirm everything in person. When I got there the place was EMPTY - no chairs, no tables, nothing! I only had a landline number for the owner and this number went unanswered when I tried phoning numerous times. Somehow I stumbled upon another number for the owner and when I phoned her I could hear she was very surprised to hear from me. She said she was "busy" typing me an email, however, she was also busy "driving". She accused me of calling her a *****, althought I NEVER called her that, I only said I demand that all of my money is paid into my account immediately. Luckily she refunded me the next day but I was still looking for a venue to host a kitchen tea. I am just wondering if she was ever going to inform me that the place is closed if I did not pitch there 2 days prior to the function. Personally I think this is VERY unprofessional to take on a function if you are fully aware that your restuarant is closing soon! Never ever in my life will I support this restuarant or recommend it to anyone!
