I would be astonished if viagogo, given their reputation around football in the UK (although it’s better elsewhere), were an authorised reseller. As such, if you enter into a contract with them expect to get burnt, I’m afraid. Had you bought direct from Chelsea you would most likely have got a refund. Viagogo won’t have any way of returning the tickets given the route they doubtless acquired them, so they before non-cancellable, non-returnable under their terms. It’s probably got nothing to do with Chelsea.
