Horrible customer service. I tried to cancel my account a month ago. Sent them an email and attempted to call them (waited on hold for 15 minutes and gave up) Followed up with another call today and decided to wait on hold until they answered. 20 minutes later the call was answered. When I tried to ask that my account be credited, she said maybe... I said credit my account or I will dispute it with my cc company. She said "fine" no credit and your account is cancelled. Sheesh... Not somebody I would want answering my business phone.
