Missing items and RUDE delivery personnel

I placed an order on the 5th of March for it to be delivered on the 6th, order arrived with missing items. The security at my estate have footage and nowhere does it show them opening it.

Netflorist refuses to take responsibility or to conduct an internal investigation of their driver Nthabiseng Moremi who has been rude to me since this morning. I believe she must have opened that package.
