Priority delivery isn't a priority at all!

On Friday 29/11/2019 we did an online order, with delivery for R338.00 (For 5x 20l of paint) Upon paying, we didn't get to choose a delivery time, but qualified for "Priority delivery". The automated delivery date was 29/11/2019. As the order was placed just after 14:00, it seemed doable - the store usually trades till 18:00, had stock and is less than 15 minutes away. On Satuday 30/11/2019, I phoned at 9:00 and was told that the delivery was scheduled for Saturday and I will receive a call before Builders deliver to confirm... Sunday 01/12/2019.... phoned numerously - no answer, but can be forgiven Monday 02/12/2019 at 10:30, my husband phones - delivery is in front of the gate. No call to say it's on their way, they are already there. Now I have to take off from work, drive back home, fetch a key, open and then get back to work. We asked if they can deliver at an alternative address, where hubby can sign, and was told "No" However, they can leave it with our neighbors, which we don't know from a bar of soap! If there was a problem with delivery, just phone the customer and arrange a time with them that is convenient for everybody!
