KFC savannah branch

I went to KFC savannah in polokwane. I waited in line at the drive thru and there were a few cars in front of me. after waiting for more than 15 minutes, they switched off the lights on the drive thru menu and closed the pay point window. No one bothered to come and inform us that they were closing, also there is no signage for the operating hours. It's not my first bad encounter with this particular branch but it will be my last since I won't set my foot there.
