Main switch on. should have put that on list.

Dunt totally surprise me tbh, Quality of some of the equipment we buy theses days is utter garbage. Coulda found that in 5 mins tho ,if in any doubt you just dab on the source with yr testers to prove it's good and work outwards from source .

Reverse polarity at the supply, or no supply voltage at all?

No voltage at the mcb, but some times where the screw on the bottom of the buzz bar is not tightened.these things must be checked has well.

Some MCCB's can catch out the unwary when they do that whole thing where the outside lever only moves a fraction and then you have to manually fully open and reclose.

More than once I've had customers ring to say the RCD lever is 'floppy' and won't latch on - always an MK one where you have to push the lever down first then up and they don't get it.
