Bad service at O Galitos Montana!!

I made a booking on the 4.05.2018 for a Mothers day buffet at O Galitos in Montana. So me and my family shows up and they told us there is no booking made. Never was I so embarrassed in front of my family Mother's day was my responsibility this year and this resturant ruined it for me and my family. I actually spoke to the manager that day of the booking. I had to phone in again and book a bigger table I have the call history on my phone and they dare to ask me if I made a booking at the right place. They said they will get back to me an hour ago and still have not heard anything. Thank you for ruining mother's day for me and my family. We use to come herr every birthday but you will sure as hell never see us again and I'll be sure to spread the word about this experience!
