Explanation:
In the sentences above, a person making a complaint states his dissatisfaction with a particular person or thing. For example in the first sentence, the speaker clearly states that he has "a bit of problem".
When accepting a complaint, the person being complained to acknowledges the problem in question. For example, in the third sentence, the speaker apologizes for the problem, thus showing his interest in doing something about it.
When rejecting a complaint, there is an outright disproval. Sometimes, the speaker begins with an apology to douse the emotions of the tensioned recipient of the rejection.
