Staff Not Helpful

We booked 7 tickets on Friday to watch Fast & Furious 7 on Saturday at 10-30 pm. When we got to the cinema, our seats were already occupied. We kindly asked the patrons to move out of our seats, to which they rep**** that a staff member had seated them there because their seats were occupied by others as well. We tried to get the staff member to resolve this matter and he couldn't be bothered. After an exchange of words, he called for the manager, who also found that filling the salt took precedence over our issue. Seeing that he had no intention of sorting out our issue, I went up to him. He came into the cinema and only asked the others why they were sitting in incorrect seats. By this time half an hour of the movie had passed. Eventually, he got us seated at Imax BUT at the 1st row from the front. We had given up A row seats for seats right at the front. The movie has so much of action and we couldn't see a thing because we were so close. What is the purpose of row & seat nos if this is what happens? I immediately went online & submitted a complaint and yesterday called the contact centre and still no response from Ster Kinekor. Who can this matter be escalated to?
