[2019] Help - Scammed by Jagex - Payed for Membership via 2 methods (PayPal & Debit Card), but not got Membership! Also Jagex Support is wank, hence why I’m here!

There's another account of yours which had three x 1 month subscriptions bought on it yesterday. I reckon you simply bought membership on the wrong account. The login emails aren't too dissimilar.

You can get a refund and/or transfer the membership quite easily.

Contact payment support. Simply say the name of the account you wanted the membership on (the one in your picture) and provide them with billing information. They'll identify the same one and get you sorted nice and quickly.
