Late delivery time and again

I booked a box of clothing for overnight delivery for a magazine cover shoot 5 days in advance of the photo shoot as my company regrettably has an account with Berco Aramex whom I have found to deliver parcels late on at least 4 previous occassions. Of course, as always the parcel went missing. I didn't get the promised call backs from their call centre, just apologies that they will follow up. I left messages on all their social media beyond my numerous lengthy calls being put on hold on average 3 times per call and holding on for a minimum of 6 minutes at a time. My parcel arrived 2 days late in Cape Town and even though collection was ordered for overnight to return the parcel to JHB on ref. no. L08CECB , it is now 4 days later and their call centre agents have no idea where the parcel is and my nearly 20 social media messages and calls have yielded no results only empty promises. Nothing they say can be believed. These mistakes cost our company so much time and money it is infuriating. My advice to anone is to never ever EVER book with Berco Aramex courier company. They fail repeatedly in their most basic service delivery and should not be operating a courier service at all.
