Overcharging Accounts

Good Day<br> <br> During late last year I placed a voluntarily soft-lock (not allowing me make calls, send sms's or surf the net) on my account that was supposed to lock my account when it reached the R50 over limit. My account apparently went over the limit with R431 (excl VAT) on data (according to their systems) but they can not tell me what was downloaded. <br> <br> My account was soft-locked on 11 Jan '15 and according to their system I've requested it to be unlocked the very same day but they also could not provide me with the voice recordings thereof. <br> <br> According to the printout provided it indicated that something was downloaded twice on 11.01.2015. The first download indicated an amount of R116 (excl VAT) and the 2nd R224 (excl VAT) all out of bundle. Their answer is that the soft-lock is not \100%""; if the first file went into access how is it that the second was downloaded even though my account has been locked? One seem to have the answers for me;sending from one dept to another."""
