POOR SERVICE AND ILLIGAL ACTIVITIES ON ACCOUNT

On the 27 of May there was R200.00 transferred for airtime to unknown accounts. I immediately phoned Vodacom which assured me that it was not transferred and must have been wrongly send to my phone. then again on the 1st of June a total of R1900.00, 3 minutes past 7 in the morning, was also transferred to unknown accounts. Today is the 9th of June and I still haven't received any feedback and as an agent it is very important for me to have a phone that works and which I am paying for. I'm still receiving messages that reads the following: \You have exceeded your voluntary call limit on (my cell phone number). Your line will be soft locked. Please refer to your monthly bill. For any queries call 082111."How is this possible if I can't even make any calls. I insist of knowing who requested the R1900.00 airtime transfer and just want to state that I received very poor service from Vodacom."""
