Angry and disapointed client.

On the 12th of April, I reported my phone ****** and requested my sim to be blocked. On the 13th I went to mall of the south to find out about replacement deals, without my knowledge a lady by the name of Gloria unblocked the sim card without doing a sim swap. Eventually I did a sim swap at PTA where I was advised my sim was not blocked, and later that week my sim card was blocked by Telkom. I contacted the Telkom and to my utter shock I was advised that the sim is suspected for ***** with a bill of R6000. I was then told to go to mall of the south were it was unblocked, I went there and they advised me that they will log a case because it was not even supposed to exceed a 500 spend limit. Till today I have not received feedback, Case ********** 1 ,case ********** 2, case ********** 2. I've called Telkom countless times no agent seems to know how to assist me , I am pushed from pillar to post .As if it was not enough this morning I was advised that the case was not dispatched to the relevant department and new case must be logged, as I was shocked I requested to speak to the manager the line was cut by the agent assisting me. today's call at 08:08 24 min,06 May 6:12PM 32 min , 25 Apr 6:47 pm 42min, 20 Apr 9:47 am 15min, 12 Apr 5:46PM 32 min. none of this calls yielded any assistance. I am so disgusted with Telkom , you have the audacity to send me an invoice of R7200 for something I did not use when your systems failed, I capped that number at R1 spend limit, it even went as far as exceeding the R500 spend limit. Your level of incompetence is shocking Telkom, I am appalled. I will not pay for something I did use.
