Double billed by Telkom

After my last encounter with Telkom and speaking to managers my installation was done successfully. My first bill came and i paid it, now i'm being charged for 2 months and when i queried this i'm being told the first charges was pro rata charges and now i'm being charged from 08/08 - 08/10 and that was never charged for the month of August. I am also being told that the bill a paid for last month was for a mistake that Telkom made when activating my data line way before i even had a land line connected, which i was told by a manager would be removed.

Looking at my paper invoice it clearly states the following: Invoice date 09 Aug 2018 Invoice number ********** 246

Home uncapped (10Mbps) 24 Jul 18 - 08 Aug 18 R(298.86) Home uncapped (10Mbps) 09 Aug 18 - 08 Sep 18 R (579.04)

So how can i be told no invoice was generated for August when clearly i see charges and i paid the bill for August that was sent to me for August. Now i'm also being told that i'm being charged a month in advance but i was not told this when signing up i made sure to ask a few times and was told its just pro rata and your monthly fee, i'm not evens 2 months with Telkom and all i see is problems.

THINKING I MADE A MISTAKE SIGNING UP WITH TELKOM!!!!
