Bad customer service from a cashier

I purchased bus tickets at the Chamdor branch. I was assisted by Paballo Bothelezi, who was utterly rude and unprofessional. She gave me such ********** service because she was not there too work but have a good chat with he colleague who mind you was working and pushing the lotto que. Paballo had only 1 customer upon my arrival, she was casually taking her time, stopping too talk then passing money to her colleague for change and just wasting time. After enduring this for almost 10 minutes I decided to ask for the manager from a lady who looked like a supervisor - I explained my situation and the bad service. We went to Paballo who gave us attitude and literally forced too apologise. I dont understand how it's a grievance to just assist customers and send them off. It wasn't the time for to be chatting away as though she was on her lunch break and too be rude about it once her behaviour was brought forward was appalling. She needs to be brought to book as no1 deserve professionalism when all you want is too be attended to with help and a smile.
