In this sentence, the speaker used "that" to additionally explain about "a friend." But is it okay to use "who" instead of "that" here? If I can use both "who" and "that," which one sounds more appropriate?

The speaker here made a mistake, "who" should always be used to refer to a person. Therefore, the speaker should have said "I am meeting up with a friend from college who I haven't seen for about seven years."
