Are these bricks rejects?

I just got a batch of class B engineering bricks delivered. I realise that of course they're not for decorative use. But they all have cracks and crazing on their faces. I've bought them before elsewhere but have never seen them looking like this...

They're to be used in a retaining garden wall. I'm concerned that the water will get into all these cracks, freeze and blow them apart.

The pallet looks really old, the paper between the layers is mouldy. I'm suspecting they've seen a DIY order and have sent the old rubbish that their trade customers wouldn't accept. It was all wrapped in black pallet wrap.

What do others think? Accept or ring them up and reject them?

They're Forterra. Here's the manufacturer's official photo of them...

It depends if you paid for perfect or imperfect bricks and also if the crazing is characteristic of the clay or manufacturing process.

The brick would not necessarily be affected by freeze/thaw because of those fissures and crazing, rather it would take other factors such as clay impurities or the firing process.

It may be down to how many of the pack have the fissures.

I rang them. They crumbled as quickly as the bricks. They'll bring others and take them away, said they've changed suppliers due to quality issues. I said they look like old stock.

They were trying it on, trying to get rid of their junk on me. The curse of trade suppliers for DIYers, sadly. I've experienced similar before with another supplier.

If you zoom in on that first photo it's not just the two cracks, the entire surface is crazed. They're all as bad.
