If it is payment before delivery no?

So I saw this beautiful shoes from UK online marketed by 'Adom Collection's', they said they were based in Ada for, so I called and they asked me to send part payment, after they are done with delivery, I will give them the rest of the money, I called them later on and no response from them, they scammed me and took my 150 cedis just like that, be careful with online shopping.
