Bosch has been making washing machines where replacing the drum bearings is not supported (the bearings are sealed in a plastic housing) for a while now, not sure if this is the case in all of the models or the cheaper ones only.
He has a contract with Upwork, Upwork has a contract with Robin, so Upwork is the one that should be on the hook for this and they should go after Robin if they want to try and recoup their loss.
