KFC Rustenburg Triangle

I recently went to KFC in Rustenburg Triangle apparently there were no Cashiers to assist us, waiter 15 mins bfr my partner asked if they were closed and said someone will come and assist us, 30 mins later there was still no one of assistance. I was really unhappy with the service as we had to leave without ordering our meal. I'm really unhappy with the service offered there, we thought drive through was taking a lot of time hence we chose walking but I guess drive thru n walk in experience this treatment too...I'm really unhappy with their service for such a big company like kfc
