Telkom reap Off

I bought R100 airtime as i normal do every month to enable to purchase my 1G data as normally i do, as i try to buy my data transaction failed so i view to check balance only to find out i have R99.61 to my suprise, so i call the call center 10 /10/2018 18:56pm to experience dissatisfying service, who i said to me was charged for USSD link twice of 20cent done 25 September 16:10pm each used for FNB, i told the consultant not possible as i have a FNB app which i use and if made twice shouldn't my balance be R99.60 instead so ask to speak with supervisor on duty but as always they can't take a call but will be called back but was not and no reference number was given as told will be called back n few minute within an hour. The next day 11 October 09:38 am called again the consultant was so rude and arrogant none cared much what i wanted or requested, logging a query for my dispute she didn't seem to care but insisting what she is was same feedback i would receive after investigatio, spent over an hour and 30 minute more holding to speak with Supervisor Thembelihle Phungula who never did come to take my call, once again was promised to be call back but she never did also, reference for case i got was ********** 0. No response on feedback until i called again 17/10/2018 spoke with consultant by name of Sane in Durban call center by now i'm fed up with Telkom inconveniencing my life as on Saturday need to spend more by airtime to top up so can have data which need to for online payments to do. I asked to speak with Thembelihle Phungula and was told she will be in at 13:00, so requested for Supervisor on duty who was told is Sihle Ndaba, holding for over an hour for him but still he didn't take my call instead was told will be called back again and they would request Thembelihle to call me back whom have never called me back or ever did take my call in the beginning .

Message from Telkom received that day: Case ********** 0 refers our records indicate no unusual data depletion/allocation. Mail TM-SOC telkom.co.za should you require usage report. Regards TM-SOC

Which I am still disputing this, they telling no unusual data delpetion, I'm not querying data usage but my Airtime which was told i used FNB USSD link, so if they doing this to their customer take cents how much they reaping us off?? Making money from us.

Kindly assist help resolve this issue please Would like evidence in records showing what is said i have purchased for 20cent twice and calls are recorded they say and listened to the inconsistency information provided.
