Fastways snails pace package delivery

I am despondent and disappointed at Fastway staff I had a package for my business that was scheduled to be delivered on the 20th August 2020 the driver didn’t pitch and made a flimsy attempt at delivering my package then he ended up lying that he could not get hold of me. Then on the 21st August 2020 I decided to follow up 1. They staff at jet park answer the phone after 15 minutes then the staff keep you holding for an additional 20 mins thenwhen they cannot resolve your query the hang up the call I was persistent in my follow up until I got through to reception and I was promised that my parcel will be delivered on the 22nd August Saturday today is the 23rd Sun and my clients are waiting I don’t know what to say to them and I don’t feel like calling again what other alternative do I have to retrieve my parcels?
