Worst service ever from Vodacom!!!!!

After 19years with Vodacom, without any issues, they decided to just take my airtime and data (which I paid for). I bought data with some of my monthly airtime. I had the 1.3gig data and R200+ airtime for about a day (or two) and then my balance for airtime and data was 00.00. I have wifi at home and work so there is no way I used all the data and airtime in 24-48hours. I phoned customer care I they assures me they could see I received my monthly airtime and that my usgae was 0. But they could not tell me what happened. They also told me they are receiving high volumes of calls simi**** to this. So clearly there is a problem on their side. A few days later they just smsed me that the case was resolved and closed. I phoned again to ask what happened but they just logged another call with a new ref number. The next day again “resolved and closed”. In the meantime I spend another R300 on airtime and data. I then decided to go to a Vodacom branch and they also logged a call. After a few days I received a message that I need to monitor my data usage (now suddenly, according to them I used all of it). They also gave me a once off good gesture of R200 airtime (which I still have not received) This is unacceptable. They saw on their side I did not use any airtime or data and other clients also had similar issues. My friend bought data in the same week and they subtracted the money from her airtime but did not load the data. They can not just take your airtime/money for no reason and not refund you. Worst service ever!!!!! Extremely dissapointed in Vodacom!!!!!
