I refer to my enquiry of (date). I do not appear to have received a reply. Please quote, and provide two samples. Our customer is interested in your product HG 234. I would appreciate a prompt reply.
Zoe I wasn't too sure if you wanted a quote for HG 234 or a similar product. You used the word 'similar' but I am not to sure if you meant to use it.
If so, in the sentence, ' Our customer....' you could add ' or a similar product' after HG234
