Bad customer service

I was at Dstv multichoice at Maponya Mall and their customer service is very bad as there's no one directing and guiding customers which quee to join when you are doing a payment, the cashier told me that there's has been a person who is directing customers which quee to join and l told her that l've been standing in the quee from around past 2 and l made a payment at 1516 in the afternoon and only to find that the quee gor customer's that are making a payment is inside as l've been standing outside for that long without being told that the quee for the customer's making a payment is inside, Then didn't separate according to what we were there for, it was just one long quee for customer's who have queries, the ones who are making payments and those with broken or unfunctional decoders. What makes me angry is that the cashier didn't want to take the accountability and apologize she kept on insisting that the was someone who was busy directing the quee and informing customers and l even asked the ones who came before me if there was someone or a staff member assisting and they sad there was no one. I'm very angry
