Update: After being a customer for a few years, unfortunately the office has not been very helpful - they always increase my insurance rates each billing cycle, and when I call to ask why, they can't give me a straight answer.
Also, whenever I have billing questions, "Olivia," the one who deals with billing is always out of the office.
Furthermore, whenever I call, they seem quite rude and tend to treat me like I'm a nuisance, like they forget that they have a job because of their customers. Melissa has always been very helpful and accommodating, but I am pretty disappointed so far with the way the office is run.
