delivery scam

I was looking for delivery to buy medicines, contacted through their Facebook post, they asked me to pay the total amount. I asked them to send me the pharmacy's QR code, but they said they didn't provide the pharmacy's QR code. I contacted the branch, they told me there was no one there and that they do provide the QR code. I searched more of their posts on Facebook and found scam reports linked to a previous number 77056327.
