Letter of confirmation rejected by FCO what next?

Hello team I was wondering if you could help me. A few days ago, I used a commercial company (London based) to submit to the Foreign Commonwealth Office a letter of confirmation of residence from HMRC because I need an apostile for this document (need to submit this document to the tax authorities in Greece). Today, I was told by this company that the document was rejected by the FCO because the officer in the FCO office could not find the name of the individual (HMRC officer) who signed my document (in the HMRC database). The FCO advised the company to re-submit the letter again in 4 working days hoping that the HMRC database will be updated with the name of the HMRC officer. Is that something that is happening frequently? I really need to translate this document as soon as possible (with the apostile) and then submit it to the Greek tax authorities before the end of April do you have any other suggestions? thanks for your time
