Wow, nice scam… $2.99 charge gives you ~24GB data , but after downloading 12GB of a game it propmted me to charge balance again.
It worked correctly because the traffic balance is charged in a view of mudfish node. If you tried to download 12 GB file, mudfish node uses 24 GB for input and output pathes.
So if you think it’s scam, then yes it could be. So please let me allow to refund your transaction if you want.
