My worst customer service experience.

on the 15th July I took 2 children to the movies to watch the 3D Minion movie, I waited in line to book electronically & there was no order, people cut the lines & there was no management visible. I attempted to book tickets electronically & the system kicked me out, I asked for assistance and was told to wait whilst others were helped before me. The staff then assisted me and the seats I selected were no longer available, my payment went through but the machine would not print, I was asked to follow a staff to the upper level where a manager was summoned by shouting across the foyer, the manager arrived and asked why he was asked to attend to the problem whilst there were other managers on shift in my presence. The staff explained the problem to the manager & handed him my card details, he failed to acknowledge me and walked away, the manager returned and said that there was no such payment, I showed him the confirmation on my phone from the bank and it was noted that the staff took down the wrong numbers, the manager then went to his office & returned with a page proving my purchase but the 3Dglasses were not included and he told me to go buy them with cash...there's more
