Can't cancel data package!!!!!

I have been phoning 10210 to speak with the cancellation department regarding my adsl account for more than 2 weeks, I get put on hold for more than 45 min!!! an then i eventually retire the call!!!.<br> <br> They are billing me for an uncapped data package that i have never used, Because they never sent me the Username and Password associated with my account.<br> <br> I am currently using Afri-host as my ISP and i would like to cancel ONLY the DATA side of my account, Not the Line rental or the line speed, ONLY the data!.<br> <br> Please can someone assist me with this.
