No service, 10210 is useless

Request for cancellation of residential line was submitted by your Northgate customer service center on 18 January. 2 months later, numerous unanswered emails to [Email Removed] 3 telephone calls to 10210 ( the last of which referred me to a Pretoria number that doesn't exist), and I am still being billed for a service I am not using. I don't even have an instrument connected to the line, yet I am being billed for calls to mobile numbers. This morning Jackie at 10210 informed me that there is no request in your system for line cancellation. What is going on?<br> <br> When will this line be cancelled?<br> When will you refund for me the line rental I am forced to pay because you have not cancelled my line, after I followed your process?
