Struggling to cancel telkom line

I don't like complaining, but I have to turn to this method in order to hopefully get a response:<br> <br> On 22 January I phoned telkom to cancel my voice line, they asked me to email a cancellation form to [Email Removed] I've done so and received a confirmation email that said a consultant will contact me within 72 Hours.<br> After 72 hours and not contacted by telkom, I again sent the form on 26 January. After this I kind of forgot about it and I just received an invoice for February.<br> Obviously the email is not working, so can someone please contact me and assist with the line cancellation.<br> <br> Thank you
