Terrible Customer Service from PnP Clothing Team

Very disappointed in the responce I have been receiving from the Clothing Online team. This has been pending for almost 2 weeks now!!!

Order #*** - I ordered 18 items but only 17 were delivered. I flagged it immediately with the team and received the following: Please be advised we are unfortunately waiting for footage from the warehouse as they have advised that all items have been packed and dispatched.

I am a paying customer and made out to look like a **** which I DO NOT appreciate!!!

Why would I complain about 1 item???

I paid for 18 items and only 17 were delivered and I want my money back immediately or I will be taking legal action!!!

I WANT THIS RESOLVED TODAY!!! I WANT MY MONEY BACK FOR THE ITEM I WAS CHARGED FOR AND DID NOT RECEIVE!!!
