I transferred and amount from my paycard to my...

We would like to inform you that you shall ask the bank about the reason for rejecting the transfer.

If the transfer did not reach your account in the external bank, you must ask the bank to return the money to your account.

Or, you may ask him about the transfer number for the question through the other bank, whether the transfer arrived or was returned.

I advise you to check with the authority that you transferred through to ask about the topic and try to solve the problem.
