still waiting for refund!

In November 2014 I, Righard Brand, identity number ***, cancelled the land line ***, a lady had the nerve to phone me afterwards telling me that there was an outstanding amount of R221,87 to be paid, I paid the R221,87 and afterwards Telkom discovered that I was supposed to only pay R157,60 which means I paid R64, 27 too much, i went to the Westgate branch in Roodepoort and explain to them that they can't credit me for that amount because i cancelled the line and that I need to be refunded, a query was logged on 8/1/2015 and I was told that Telkom would contact me - well I am still waiting, does it take 2 months to investigate a query? I mean it is as clear as daylight that they made the mistake or do they silently hope that the client wil forget about the owed money? They are very quick to disconnect your land line if you fail to pay on time but it is fine for them to let the client wait for 2 months for owed moneys? I want my R64,27 with IMMEDIATE effect!<br>
