Legal Advise for consumer court case

Dear sir, thank you for giving me a platform. I am a sole proprietor of company name Continuum Surgical. A year ago I had verbally deal with one company name Promed which is based in Congo , Africa at Ahmedabad. In that we to make material of medical gloves in their brand.After receiving payment we made but they have own exporter name Shiv Exim so we have to send materials to Shiv Exim and had to make invoice in the name of Shiv Exim. So after we checked materials we sent them through close container to Mumbai at the address of Shiv Exim. After received materials by Shiv Exim , we had not any information that they sent materials to congo or not , But one day after a few months we received mails from Congo that materials was damaged not accepted. So they argued that we had to take all that materials back from them and replace with new. As we sent inspected and okay materials how can they blame like this. Even they ordered that we have to pay all money back which was used in this order.
