Vodacom stole airtime and won't help

On Aug 10 I read an article about ********** WASP services. On a whim I sent a STOP ALL and received an SMS saying that i was disconnected from SIX WASP services I *never* subscribed to. I checked my airtime which had been in excess of R900... and found it was about R200. It is now zero. I phone 111 and asked them to check itemised billing because my airtime was ****** and I have no way of seeing where it went because I refuse to pay the exorbitant cost of itemised billing. It is a service I never need unless I have a query like this. They refused. So Vodacom's attitude is "So you lost R900? Too bad. We won't help"
