Requested limit on My Gig not set by vodacom

I have been struggling to sort out the account problem with Vodacom regarding my gig contract since 16/08/2015 that went over R5300. Firstly I went through the same problem last year in October whereby this particular contract line was over a R1000 and on the 2/10/2014 I called Vodacom to enquire and was told that there was no limit put on the number. I then asked for the limit to be put on the number and went ahead and paid for what I owed. Surprisingly, on the 16/08/2015 I discovered that the same line went to over R5300 and when I called to enquire I was told again that there is no limit on the line. I explained to the person that I went through the same experience last year and specifically requested a limit to be put on the line and I requested a recording of the 2/10/2014 and I am now been told to get a lawyer if I want access to the recording. Why should I pay a lawyer to access the recording that should be \for protection an quality purposes"?. I have two other numbers that are tied to this account and I will be unable to use my numbers because I am told that they will be suspended together with the my gig number even if I can pay for them."""
