Scammer fake order for small home bakers

basically I got an order from a person near by he wanted a doll cake I agreed we discussed the details and agreed he will pick up and pay in advance Tommorow the next day I made the cake but i noticed he didn't paid at the time he said he would do I sent the pic of the cake he saw the message then didn't responded yes he blocked me !!I called him with another number and he answered then and said i didn't order [TXN_ID]!!!! [PHONE] this is his number I got scammed and my 700 and time , efforts got wasted on a fake order
