wrong billing

i complained about the billing on hello peter, the consultant called me when i was in a meeting, i asked to be called back two hours later. she never called. fine, but i was debited all that money from the incorrect bill on the 15th of March. i mean which debit order goes off on the 15th? i am so over telkom. now i have to go to the bank to reverse the money, i will reverse it until i get a call to explain why i was debited that much.
