I can not believe this idiot called back two more times. then proceeded to yell at me about canceling his ABT service

he told me that was the number he was given and wants me to take care of it. i got kinda sick of this guy so i told him hes stupid and calling my cell phone, not any "ABT Office"
Then his dumb ass proceeds to read the number he has and has a 301 area code, not 310 (which is mine). Then just says "oh sorry" and hangs up. not even 5 seconds later he calls back...
This time I answer "ABT please hold" and put his dumb ass on hold and he calls back again but i must of missed the call and left me a voicemail
