Agent DIFFICULT to talk to.

EXTREMELY DIFFICULT conversation with Cindy (Sindy?) in upgrades department. EVENTUALLY, after MUCH frustration, I asked to speak to a supervisor. Denied the right to speak to a supervisor. Cindy (Sindy?) will send an e mail to the supervisor, apparently theres no supervisor near to Cindy (Sindy?). FLIPPING FRUSTRATING. I EVENTUALLY hung up as i was too frustrated to continue talking. In addition, at NO time did Cindy (Sindy?) advise it was a recorded conversation.
