I bought two mobile passes a few days ago, with the starting travel date on 14/8. I also purchased the Plus upgrade, so 100% refund should be possible. However the return policy page has been unavailable for the past few days: https://www.interrail.eu/nl/interrail-passes/ordering-info/return-policy
I tried to contact the customer service several times, but I only hear back from you after 3 weeks.
Please help me cancel the global passes
