Incorrect billing and cancellation.

In October 2015 my adsl line and telephone was off not working due to a faulty cable, I reported this a month later Telkom fixed my line. In November they billed me for the full month whereas I had no internet or telephone line. I called the call centre spoke too many agents asking why must I pay for a full month when I had no access to both my lines.I was told that a credit manager would call me up until this day no one called me. Telkom is still billing its January 2016 already 3 month later R2400 for a off line. I then cancelled both lines in November 2015 sent threw all the documents required for the cancellation process received a sms and email that they received my documents. I received 3 different bills thus far not sure for what. I went to the head office in Claremont they said they can see that I cancelled and that I must wait until febuary 2016 for a final bill. This bill is reflecting on itc showing that I'm in arreas, so fedup and tired of telkoms bad service all round.
