I do not understand this part: > "I’m on very good terms with Robin." So why Robin does not want to pay and help with Upwork if he is on very good terms with him? If you are in very good terms with Robin, then just ask him to pay for work. If he refuses (and he is not scammer), you can open a case in Upwork and then you will go in arbitration. The arbitration is quite reasonable and works well (I had to run one). But if Robin is a scammer - then I'm really really sorry for you. There is very little you can do without lawyers and law enforcements.
