It is possible that a credit or debit card that was accepted before, may be declined or stop being approved for further top-ups. This happens for many reasons, like the card being restricted by your bank recently, exchange rates resulting on a charge higher than the available balance in your card, an incorrect CVC or expiry date being entered, among others.
For more information, we advise you to contact your bank directly and clarify the possible reasons for your recent declined attempt to make a purchase at MuchBetter.
You may try using a different card issued by another financial institution or bank.
In addition to VISA and Mastercard, you can use other alternate top-up methods including cryptocurrencies like BTC, ETH, LTC, USDT, XRP, BCH, USDC, DAI and XLM to top up your MuchBetter wallet using the “Crypto” option on your MuchBetter app.
