I purchased £15.99 crom coins last night and it said the purchase had failed so I repurchased only to find I now have been charged twice and have double the cron coins required , I find this very underhanded and very hard to be refunded
Did you talk to your bank? I remember this happened to me buying a smart phone back in 2009. My bank didn’t even wait for me to call them and started going after the retailer in a bad way who called me to get the situation rectified.
Using Zendesk might also work to get Funcom to fix it on their end.
