I ordered a diamond tester, but I received a screwdriver instead. This is the wrong item and not what I paid for. Please arrange a full refund or send the correct product immediately.

I'm trying to return this product of terrible quality and it always gives an error. The product is defective and doesn't upload any videos or photos for me to get a refund. Very bad, terrible service, one star is too much for this kind of service.
