Extremely rude customer service. Recently asked to have my cell phone number removed from their database, as they were blowing up my phone daily. Three reps and one supervisor later, I'm still getting daily calls and voice mails despite requesting my number be removed (for weeks) from their primary database. I was professional, patient, clear and soft spoken even, however, the last rep and supervisor were beyond rude. There are no excuses for unprofessionalism from a supervisor. HORRIBLE SERVICE. Run away.
