@OP aside from additional screenshots I think you also need to provide other evidence such as the tx id of the transaction to them which I think would be convincing some people here. Right now arcticminers totally deny all of your accusations and this would totally turn around if you give additional evidence with what happened. Aside from the tx id I think the conversation of screenshots will be good, also @articminers aside from totally denying and claiming he is doing a fake review why don't you just solve it by asking his username to see if his transaction is even real.
