But, The OP Claims he Provided This Address But he Didn't mention What address this is such as is it ETC? USDT? ETH? Then How UnioChange Know This is an ETH Address?
we need to separate first, whether there are elements of scam here. OP clearly says "UnioChange exchanger is scam!!" and accuses them of scamming him for the amount of $1350
What happened:: Scammed 1350$
So, again question is, whether op has access to Ethereum at that
0x4c15B9B6E6177f20E745254758ed84b3e33a447E address?
If yes, (and it seems to be yes), how they
UnioChange can be labelled as fraudsters? they did not take his money and went away.
the way they finalized the transaction is something else entirely. very poor communication, sending the wrong currency and finally sending through Binance, everything looks completely amateurish. it is definitely recommended not to use this service due to the incompetence of those who lead it, but not because of possible fraud.
