I avoid resellers when possible. If they can’t communicate, even more so as things are ‘lost in translation’.
If the order is complete, to this buyer’s specifications, it’s not your responsibility if their buyer didn’t like it. Your job is technically done. Revisions do make the process more difficult. In the ToS:
- Buyers may use the “Request Revisions” feature located on the Order Page while an Order is marked as Delivered if the delivered materials do not match the Seller’s description on their Gig page or they do not match the requirements sent to the Seller at the beginning of the order process.
Your buyer is technically abusing the revisions option, and also failed to fill out your initial contract (requirements). I know Fiverr CS probably wouldn’t agree, but I see this as making the contract void.
You could redeliver the order. If you want, you can state in the delivery message that he does still have two revisions left if there are still changes needed (within the scope of the order), but that all instructions for changes must be delivered at the time of the revision request.
In summary: His client shouldn’t be your problem.
Side comment: I glanced at your gig and didn’t find anything in it that defines what a ‘revision’ is. If it’s in your requirements, that’s fair, but there’s a lot of risk you’re taking on without the boundaries. Have you ever had issues with buyers asking for more than you offer?
