Unable to access site even after fulfillment of unpaid due

Today morning our site got suspended due to unpaid due. So, I paid the due with via my visa card. After the payment was successful, I was able to access the site for a short period of time. After a few hours, the site became suspended again, and it no longer opens, even though it shows that the payment has been made.

Please let everyone know if this is resolved and the steps you took to resolve it.
