Telkom

Good day

i hope someone can assist me with the following... this morning my wife noticed that a payment of R 2 166.00 were deducted from her bank account from a telkommobi ref number, the problem is that we do not have any account with Telkom or any subsidiaries, we have tried numerus contact numbers and no one answers. we would like this to be sorted out immediately, how can Telkom put a debit order in on someone if that person did not authorize this.......

how do i get in contact with someone at Telkom, or how can i get someone to contact me?
