Shortchanged and dismissed

I bought USN's creatine monohydrate from P&P ASAP, on the app it clearly says "100g + 100g". USN runs the same special (2x 100g tube) on their website and the price is similar. I received one 100g tub for R219.99. Unless PnP sells it for double the price as the supplier and labeled it wrong on the app, something seems wrong.

I contacted customer service and was told "The item is labelled as one. Check the weight of the product". Then she simply closed the ticket, my e-mail response was blocked and undelivered. Maybe PnP should "check the weight of the product"!
