Appalling customer service - Valentines ruined

I made a booking almost two weeks ago for Valentine’s dinner with my 6 year old daughter. I’m a single mom and travel a lot, just returning from a trip again last night. I was looking forward to spoiling her with dinner in a beautiful setting. We arrived at the venue and our booking was never captured and to my surprise what the individual who did my booking telephonically failed to tell me was that there was a set menu at a cost of R540/p which obviously didn’t have a kiddies option either. We spoke to two waiters before I finally got to speak to the manager who seemed extremely inexperienced and in his attempt of saving this situation went to speak to the chef just to came back and say that the chef refused to assist us as they are fully booked and was also unwilling to attempt making a kids friendly meal. The manager then proceeded to say they have a new staff structure who are all very inexperienced and they are attempting additional training to fill in the shortcomings so sorry but he is showing us away. I am appalled by your customer service and you truly deserve this poor rating. Thank you for spoiling our Valentine’s Day.
