I have just learnt that vodacom has been billing my company for something I did not subscribe too. They have done this to multiple phones. From the begining of this year I have been charged over R1500.00. When I called my service provider he informed me that this is happening to a lot of people. He then asked me to login into *135# to check what it was and then to unsubcribe to it. First of all i did not subcribe to anything and then got charged for this. Vodacom has done fruadulant activities on our phones. They need to be reimbused me for this, also I think we need to lay a charge against VODACOM. this is not the first time this has happened, the last time they charged us out of the blue for DATA when we did not require data or use data. NOW THIS!
