Definitely go in person and dispute it. My bill jumped $50 one month. Then the next month was much lower. I happened to stop by the office to pay my bill a month or so later and asked about the difference. They said they overcharged me and then credited me the difference the next month. Problem is they overcharged by $43 but only credited me $15. Definitely need to speak to them in person.
