Telkom not cancelling my landline

I have a landline with telkom and submitted the request to cancel it effective 01/04/2018 twice. I emailed it myself and the Telkom store in Centurion also mailed it when I got no feedback. Still nothing was done. I asked for help on social media and was told that the request was updated, with reference no: ********** 23A. Please see conversation copied below. The request still shows that I app**** for a new product and they are busy checking stock availability. Please help me,

"I have requested to have my landline cancelled from today (1 april). It is still active. I checked on your website and my request was " pending for a new product, subject to availability" ? Nobody comes back to me on this. Please help me ********** ********** 880561

Hi Ina, the cancellation has been updated the reference is ********** 23A ^Lebo

Thanks. When will the line be cancelled now?

That reference number still says "checking stock at our warehouse". Who can help me with this? I want to cancel, not order something new"
