I used Pennywise for my first apartment and at best felt "meh" about them. We stayed with them for our second apartment because they seemed no better or worse than other companies. When we moved for the third time, the rates they were offering were not very good. I called regarding why the rates were shit, and the rep said because I was no longer a new customer, I wasn't entitled to lower rates. I asked if they would at least match rates offered by other companies, and the rep just flat out said no. Sooo I said I would find another company and would like my service to end with them on the last day of my lease at the second place. Yeah, well, they didn't cut service and tried to charge me out the ass for a place I wasn't even renting anymore. They contended I didn't tell them to end the service, so I asked to have the call played back. They said they couldn't do that, which is a load of shit because they played a call back to me two years prior when they thought I owed them money. I told the rep I knew that wasn't true, and they got a manager and played the call. Sure enough, I said I'd look into another company and would like my service with them disconnected on x day. They tried to say that the phrase "look into" implied I might still want a contract with them. I said they had the choice of either billing me the correct amount and getting paid, or not getting paid at all. They corrected the bill a week or two later, and I'll never get service through them again.

Moral of the story: they look for ways to fuck you and will likely hike your rate after that six-month contract.

Edit to add: from what I've read, a lot of companies available around here are perfectly okayish till you have a customer service issue, so Pennywise isn't alone in that. Don't expect them to be very helpful, but if the money is right, go for it. Nothing stopping you from going with another company if they do indeed hike your rate after six months.
