The Courier Guy is killing my business!!! No accountability for lost parcel

I dropped my parcel on the 23rd March in a locker and it was deposited in Cape Town locker on 26 March at 10:07. When the receiver went to collect the parcel on the 28th March at 12h50, they locker was empty with no parcel. When I track the parcel, there is an update "Collect and return to hub" at 10h21 on the 28th March....

I have been calling them since the 30th March and they don't know what's going on. NO UPDATE, NOTHING WHATSOEVER!!! I always have to waste a minimum of 30 minutes of my time and airtime to follow up, and believe you me, nothing comes out of any of those calls. I've been requesting to be transferred to the Cape Town hub, I'd be put on hold until I end up dropping the call.

I sell Forever Living products and have been using The Courier Guy to deliver the products nationally, and now this is now killing my business as I don't trust that my next parcel will arrive to my customers. Now I have to refund or suffer a loss as I need to recreate the order for my customer!!!!!!!!!!! really????
