Fraud that they wont fix

They charged 800 dollars on 4 of the cards I had on the account when it should have taken it out of one specific card. When I contacted them, they took no responsibility and said they couldnt do anything about it. Now all cards of mine are frozen due to fraudulent action and theres nothing I can do. DISASTER. AVOID THIS APP AT ALL COSTS.
