Vivaly review for Chargeflow Prevent Chargebacks

They are scammers! There service doesn't work, but you pay for it! They charge you 29$ on each dispute ! without any action from their side!! You don't get an alert before it's shown on shopify, and they don't make a refund for the customer. So, they just make it worst for you, and charge you extra 29$ additional to bank fees and return amount!!! Contact them many times, and even I deactivate my account with them, they still charge my credit ! I can't get off from this very bad service!!!
