I had paid for the annual Chess platinum membership on august 12th. Today it's gone. There's no trace of it. How do I go about resolving this?
Please help
Generally, something like that mean the payment method had issues or a refund was requested.
Either way, @Rimuru is correct and contacting support directly is the only way to be certain and get assistance.
