Horrible customer service

Horrible customer service, the ladies are not professional at all. Sent an overnight parcel on Thursday and paid for overnight delivery, the parcel apparently only left the shop on Friday. I called and asked them to fast track it as it was supposed to be somewhere on Monday, I was sent from pillar to post and they even hung up! 3 of them kept swapping the phone around and giving me different stories. Why am I paying for overnight if the parcel will take 3 days?? It’s even useless now because it was for a submission and the due date has expired. Waste of money and time!
