Complaint about FastWay Couriers

I purchased online via ShopShipShake, my parcel gets to me through FastWay. I don't normally get problems but this time i am so disappointed with them. My parcel was picked up on the 7 Dec and i expected delivery on the 10. I never heard anything from them only when i track my parcel they wrote"could not locate condignee". I have been trying to call them to get my parcel and i was transferred from department to department until i was transferred to this lady Rovanne who works in Cape Town depot. She was so rude to the point where i asked to transfer my call to someone who is willing to assist me, and she asked if i want her to transfer me to the deadEnd...after that she put the phone down chatted to her colleagues about 5 minutes and eventually came back to me to say i wiil get my parcel on Monday 14 December. I tried to explain how desperate i am to get my parcel since i will be leaving this afternoon and she couldn't pay attention to me. I reported the matter to head office still i couldn't get assistance i was told by the lady who called me back that they will give me feedback later i still haven't heard from them... Unfortunately i will have to cancel my trip no one is telling me how they couldn't locate me when they have a correct contact details and address... I am so disappointed with them
