Does the inconsistency of form e certificate of origin and C

We have goods exported to Thailand. Now we encounter a more difficult problem. The problem is: the customer asked us to provide the form e certificate of origin, but our company has no qualification to handle the certificate of origin, so we can only buy, but buy the form In the first column of e-Certificate of origin, the consignor can only show the name of the certificate company, while our title can only be displayed under the description of the goods. The customer said that such form e certificate of origin cannot be exempted from customs duties. Later, the L / C company suggested that all the customs clearance documents should be made in their title. However, the customer asked that the money should be transferred to this account, otherwise they would not be able to enjoy tariff reduction or exemption. However, the L / C company said that they could not accept foreign exchange. What should we do now?
