ARCX and ARCX3 token problem

Hello there are two types of ARCX token new one contract number : 0x1321f1f1aa541a56c31682c57b80ecfccd9bb288
Old one contract number : 0xed30dd7e50edf3581ad970efc5d9379ce2614adb
So i send ARCX funds from my Metamask wallet to Gate.io they deposit my ARCX token to ARCX3 so i don’t do anything because there is no option for trading ARCX3 So how can i exchange token from ARCX3 to ARCX Gate.io allow ARCX3 withdraw just ?
