We understand it can be frustrating not being able to use the payment method you want.
The on-ramps platform is a third-party service we use to offer more payment solutions, but sometimes those third-party services may choose to refuse payments from certain countries or certain cards.
We recommend you try with a different payment method and if that doesn't work, test with another on-ramp solution since all three options we provide - Ramp, Wyre, and Transak - are different.
You can send crypto to your wallet using a local exchange if that doesn't work. You can read more about how to add funds using crypto here.
