What are the speakers discussing?

M I got my utilities bill today. I can’t believe it, it’s so expensive.
W Mine was, too. Maybe it’s because I’ve been using a lot of electricity lately.
M So have I. But I still don’t think I should have been billed this much. Maybe I should call the hydro-electricity company and find out if the rates have gone up.
W That’s a good idea. Their customer service representatives are really friendly. Let me know what they tell you.
