Bad customer service

I ordered KFC online and I waited for 2 hours at the delivery spot (Century City Taxi Rank). I had to buy airtime twice to call customer service and none of the 3 agents I spoke with tried to escalate the matter.They just promised to get back to me. I literally had to walk back to the mall (Canal Walk) to report at KFC.The manager just looked at me and just told me there’s nothing she can do,I must just call customer service,the very same customer service that do not know how to resolve issues.The manager didn’t even bother to apologise. I’ll never ever order from KFC again.
