SHOCKING ONLINE EXPERIENCE

Placed an online order for 10 items of a product, i received 9. I logged immediately with a phone cal and spoke to an agent and explkained urgent to get the balance. He stated i will be contacted shortly , that was 3 days ago with no contact . In the interim I chatted on their wattsapp 2x with no luck , sent 2 emails to the *** and when no contact sent another and included ***. now 4 days later no email response , no phone call and I am left with a shortfall on an order i paid for!!!
