Dear Mr..

The given offer is interesting for us, but our purchasing director has not given positive reaction to this offer. In my opinion the reason for this kind of negative reaction is most probably the fact, that he is protecting his sources and doesn’t want to quit other sources or there is a special relationship between him and this other companies. For now we do not know the facts it is an assume from ourside. Anyhow we are working on this subject and give efforts to win him for us.
