Telkom service SUCK

I`ve cancelled one of our site phones ion the 6th of July 2015. Sent the email got the automatic reply on the 7th of July 2015. Left it there because that is what I did with a previous line I cancelled. So to my surprise I got a Tax Invoice in October for the line I Cancelled in July. Phone Telkom and asked what was going on, the lady said I should email them again , so I forwarded the first email I send to them again on the 5th of November 2015. Got no reply from them. In middle November I received another Tax invoice so i send them a email again and received the automatic email from them. In December the same story i received a Tax Invoice! I went to Telkom in Bayside Shopping center and the told me they will send a request in for it. Well i was there in January 2016 and still nothing. How long will it take to cancel this line???? They said they will call but still to this day nobody called as. Do you guys not care about you clients?<br>
