Bad service

Walked in the store at Parow Cape town wanted to change the tshirts I bought the guy who was helping me said they didn't have the size I was looking for and I asked him we look further he just brushed me off boom I found one he didn't know what to say went to the till point the cashier Sindiswa was very rude she chose to help someone who came after me while I was waiting for her to finish with the person she was busy with I stood there for more than 10minutes but she choose to help someone else when I asked she said because she was buying airtime she didn't care that I was standing there for long never apologize for that matter
