Missing inventory from inbound shipment

This is driving me mad

So basically every other shipment sent to Amazon is having issues with descrepancies. The first few times one or 2 units, fine no problem. I took it on the chin as it was onlh a few quid. This time my products 'going missing' in Amazonwere talking upwards of £200. Either the staff in the warehouse are very poor at their job or they are stealing.

Either way I need my stock back or a refund. I keep filing a case and they keep sending me around in circles. Ive sent them everything they ask for but i get the same automated reply.

How do Amazon get away with this. The biggest scam going.

Finding it really difficult dealing with Amazon when things so wrong. Can someone help me what avenues to go down to resolve this.

Thanks
