If it were possible to issue a score less than one star, I would. I believe there should be an option for negative stars. I would give them a -5 in terms of customer service, issue knowledge, professionalism, etc. The CISSP certification was high on my list of priorities until this experience. The customer service representatives were incredibly rude and refused to assist me. When I asked to speak with a supervisor, they placed me on hold repeatedly, often for 3 to 5 minutes at a time and frequently throughout the call. On each call, I was placed on hold at least four times. I have never been more disappointed or dissatisfied with any service, regardless of the location of the call center. This behavior seemed purposefully rude and disrespectful. I am so frustrated that I would consider taking legal action.
