this happened today in megapolis. i saw Azn1Gunner advertising that he is selling a level 100 box for only 10m. i got interested so i told him that i will buy. so, he traded me and told me to pay 9,999,999. the first box was a level 100 box but when i put the money, he changed the box to a level 15 box. i was quick to take a screenshot. beware of fakers, another form of scammers..
this is the scammer Azn1Gunner
the real level 100 box
the level 15 box (he switched boxes when we were about to trade)
