Beware of online sales

I placed an order via whatsup on the 25 Jan 24, I paid the money and even on my bank statement it shows an amount of R502.47were paid via the link they send me on whatsup. Up to date I didn't receive my order. The order no. Was 94556. Please guys be carefull. I tried to communicate my issue via whatsup, email no fruitful outcome. I'm just left with one option of opening a police case cause I'm a pensioner who really worked hard for that money.
