Client received the completed work but not paying

Hello,

I have completed the work for my client and raised the invoice.But the client is not paying the invoice and it has been pending since 2 weeks and he is saying that he has problem with the credit card.I have also contacted the PPH customer support but I didn't get a proper resolution for my ticket.

I think I won't get paid for the hard work done as credit card not working for 14 days is an excuse.Even the Escrow amount is half of the work done.

Looking for solution.

Regards,

Vineet
