Bad customer service Sandton Ster Kinekor

I visited Sandton Ster Kinekor on Tuesday 1 May 2018 to see Avengers at 9.15am. 20 minutes into the show, the movie stopped playing. We were told there was a technical difficulties and the movie could not continue. No apology was offered. The staff were arrogant. No refunds could be given. We were not reimbursed for parking or refreshments purchased and were told we would be offered a voucher for another movie. I understand that this was unforeseen but the way staff handled it left a lot to be desired.
