We have to give a group presentation next week as a group of 6. Two of the members have not been turning up to meetings and ignoring WhatsApp messages and emails sent to their university email address. They will turn up to the occasional meeting, but miss most of them. Most of the time they won't message or give any reason for missing the meeting, or they will let us know during the meeting that they can't attend due to work, a society meeting (where they were doing craft activities, so nothing compulsory) or an appointment they would have know about in advance. They make no attempt to reschedule the meeting or flag to us in advance to ask us to change the date/time.
Their contributions to the presentation has been pretty rubbish. Both aren't really relevant to what was asked of them and they both have misunderstood what was needed (and we've not been able to clarify as they're not in the meetings).
We spoke to the lecturer as our attempts of speaking to them on WhatsApp, email and in person haven't helped. They responded that they were frustrated for us, but if we want a good grade we'll have to just get on with it and do their sections ourselves.
