Making Card Payment from Nigeria to Upgrade free Plan to Paid Plan

For over 1 Week now I have tried all I can To make payment and Upgrade my account. All proved abortive as I get this error every-time I tried making payment

"our transaction has been declined. Please contact your bank for further details.
Or, to proceed with the payment, you can pay with a different card or PayPal account."

What is God's name is this. I called your sales Support they had no idea on how to get it fixed, I mailed you guys with my User ID nothing was done. This is the worst platform you can ever imagine.

What should be more easier to get done if not payment? All Cards have used have rejected with same error.

My client is growing out of patience as he claim for a refund for my services.
