What would the woman like the man to do?

Câu hỏi :

Question 27 - 29 refer to following paragraph:

M: I just received my invoice from the gas company in the mail. I can’t believe the cost
W: Mine was quite high, too. I think it’s because I’ve been using my heater so much in this cold weather.
M: I have as well. However, I still believe it’s higher than it should be. Maybe I should contact the gas company to see if they regular rates have increased.
W: sounds like a good idea. Their customer service department is vey attentive. Keep me updated on what they tell you. What are the speakers talking about?
