Narrative:
Reporter stated that his main concern was the nonchalance of the trnee and the lack of any warning that a conflict was in the making. The instructor controller did not intervene and this also made the reporter mad. When reporter called the facility to get the story, he was made to feel that the supervisor was being evasive. All in all, reporter was very unsatisfied with the ATC service and the follow up telephone call.
