Happy and pleasantly surprised....
When I called Constellation customer service to inquire if I would be able to get their new, lower rate since I had just signed up for their service less than a month before, the gentleman was very pleasant and helpful. They did give me the lowest rate and I was both pleased and grateful. 🐦💗
