Pathetic service on refund from Pep in Meyerton

We currently have load shedding from 08h00 until 10h30. I was at Pep Meyerton after 08h00 this morning to get a refund on clothing that is too small . There were no bigger sizes, that is why I requested a refund. When I came to the till the operator informed me that the system is still starting up on the generator. He said he could not perform a refund because of this. I asked if I could wait for a while and he confirmed. At almost 08h30 I returned to the till and asked if he could do the refund already. He confirmed. Then when I stood in front of him, he said "Sorry, it is too early in the morning. I did not sell anything yet, so I don't have money for a refund." I asked him don't you get floats? He said no. Really? How do you run a business or a till without a float? This is truly pathetic service from a PEPKOR company.
