TELKOM IS DISHONEST TO ME!!!

I have reached a point of getting used to telkoms disappointing service it's disheartening currently have two issues with them, no.1 issue that I have currently is that on the 2nd of June this month I realised my Data was not loaded correctly and had unmatching amounts only recieved 25% of my Data and not the rest which is 25gigs worth of Data but obviously understanding such errors can be made I contact them via their chat site and request for them to rectify this then their consultant confirms this to say " I realise on the system that your 20gig Data was not loaded this month however i will escalate this matter" obviously i have a huge sigh of relief to see their acknowledge their error and will fix this only to get a BIG SHOCK this morning via SMS this morning which read "Case ********** 3 refers our records indicate no unusual Deal Data (TML ********** )allocation.Call 081 180 should you require any clarity on usage .Regards TM-SOC" i almost fainted in disbelief I then call them since they never had the decency to call and tell me this and spoke to a Lady who confirms their message to tell me you used all your 30gig is less than 72hrs i then proceeded to ask her to escalate this matter because i know i have not used this much data not now or ever within that short space or period of time which they should know as i have been with them for more than 3years and secondly her colleague confirmed with me that their records showed her this she then Ayanda then told me they have done all they could have done and theres nothing else that can be done not even put me through to a manager, I'm extremely fed up with telkom and their stories and at this point want to terminate all relations with them forever because secondly then have been nothing but trouble to me even when it comes to transparency of their activation charges. Such a huge company taking advantage of a citizen im beyond disgusted.
