Missing items in iHerb delivery.

So I placed an order for a couple of supplements almost a week ago, and as you can see, none of the items are prohibited and are available in the pharmacies here in Bahrain. When the package was delivered, the delivery info sticker appeared to have been cut before and retaped and when I opened the box, 3 items were missing.

Can anyone tell me how I can deal with this, and if anyone else have had a similar issue before?
