Basic proof of delivery and inconsistency

I booked in my iPhone6+ as Paarl Mall to fix a cracked screen - insurance claim. I was given a document signed by the staff member and had a SMS confirmation re job number BEFORE I left the shop. Took them very long as Tygervalley Repairs had no stock. Terrible, if I have no money to pay (my stock) I can't claim out of stock, but they can. Then I receive SMS its back at Paarl Mall Vodacom on a Friday morning. Arrive at Paarl Mall on a Friday afternoon, no its not there. No one tells me there is now delivery on a Friday afternoon or Saturday
