Disgusted Turkish Airlines Ground staff LAX

My daughter flew out of LAX 12 August, 17 year old minor. As a surfer she carries a surfboard bag with several boards inside the bag. Normal procedure is to pay fors sport equipment around $150. This time though the ground staff wanted to charge her $780 dollars, as they wanted to charge her per board in the bag. Bare in mind this only weighed 20kgs. When she said there is no way she can afford this and that her boards where initially waivered, they would hear nothing of it. I spoke to manager and worker over the phone, both not willing to give me their names, who said tough you pay it and thats that. I mentioned this is not advertised and do you charge a golfer per club, they said its a different sport. And proceeded to tear up her boarding ticket in her face. I fortunately got hold of the South African Manager, who followed this up and got her through after 1 1/2 hours and lots of trauma, the staff told her to stand there so they can take her picture, what the hell, how bad is this, she was in a state a minor.
