Needless to say, AT&T has been trying to reach me to discuss this CSR's rudeness. Unfortunately, they've been calling me at wacky hours from a number listed as "Unknown". I don't answer Unknowns or Private calls, sorry. Nor do they leave a call back number on the voicemail, just a "sorry we missed you again" message.
This morning's phone call to discuss the issue? 4:51 am.
