One of the customers with whom I have just started dealing has a very combative stance. They've had a couple of issues and my company has not been without blame but I've been honest about that and want to work with them to improve things and operate as good partners iyswim.
He's relatively junior and not used to managing suppliers and I think he is taking his cue from his manager who also has a combative style. I need to reply to his email in such a way that I can try to reset the relationship on to a more positive track and have been mulling the best approach all morning. Any hints or suggestions from those of you who have dealt with a similar situation would be most welcome.
