I very rarely leave a message. I only really phone people at work. I text friends etc.
One occasion recently springs out, I was trying to get through to someone from HR at work. She's our regional HR person, the only one that can do the job. It was very important since none of our staff have been paid any overtime or sick since the beginning of december! So some of them owe us hours, some of them we owe.
Basically we need their names adding to the piece of software on our back office computer, that processes this information. But this woman NEVER answers her phone. I refused to leave a message though, since it was very important, I didn't trust her to ring back. When I eventually got through (2 weeks ago) she told me to email the info. Its still not done.
One of our staff has just left, oweing us 30+ hours in sick.
Mood media supply our instore satellite radio, when we need to log a call, no matter what time, it is put through to the "out of hours" message service. Idiots. But I have to leave a message because the satellite reciever is out of tune, and we cant tune it! All customers hear is a garbled noise!
