Bad delivery service

I had bad experience with my delivery, send the parcel for urgent which was charged price for 3 to 5 days. Those days exclude weekend and holidays, fine but the delivery delays when I enguire I was told about terms and conditions which gave me a fried that my parcel was lost, they were not be able to trace it on their system no waybill registered lucky the parcel arrived nine days after too many hassle and noises of me calling every day wanted to find out if they managed to track and find it. Response was they are waiting for response email from courier collected it. Just imagine the stress and panicking. It was too bad
