Table not ready after booking and bad attitude

a Month ago I phoned spur to reserve tables for my son's birthday party on the 27/2/16 at 16:00. When I got there our tables was not even set up and ready for us. When I complaint to the manager he explained that our tables was given to someone else and that the situation is out of his control. I threw a scene and wanted my table to be set up in 10 minutes time. He moved us after standing and waiting for 20 minutes to another table. I instructed that I want the table close to the play area. I had to threw another scene just to get the correct table. After 30-35 minutes we eventually got our table. After I already got annoyed with the service and unorganised matter the spur was handling their reservations a kid from some other table thats not from us take my daughters quarter of her burger out of her plate. I complaint to a manageres there and she started to give me attitude and tell me if I can't find the kid I must still pay. I had to fight again. I am disgusted with how the manageres handles the situation. I had to fight the whole time and could not even enjoy my son's birthday party. I am disgusted and annoyed with the way the managers handled the situation.
