BAD BAD BAD SERVICE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I got a call from a gentle men in December 2017. He asked if I would be interested in paying a little bit more to get more data a month, said he can see that I use more data on my contract. Beginnning Jan came and the extra amount was deducted, but there was no data nothing available. I had to load airtime data ect ect. I then started phoning Vodacom, spoke to about 15 different people since then, including several "Team Leaders". I was told that the person that phone me was not from Vodacom, he was from a outsource company and that they can't trace the call. My contract was change without me consent and a R1000.00 more was deducted from my account in January. Since then I'm waiting for answers and a refund. All they tell me it would be refunded within 48h00, no one every gets back to me, I was even asked to send a e-mail to customer services, still waiting for there reply. My argument is if I owe them money, they will block my phone, but now because they owe me answers and money, no one is worried. The sad part is I left Telkom because of bad service and now I've got 3 contracts with Vodacom and they don't give a dam!!!!!!!!!!!!!!!!!!!!!!!!!!!! No answers since January 2018, it's middle April 2018. They've got no idea what doe customer service means. I wonder where they get there training????????????????? What a JOKE!!!!!!!!!!!!!!!!!!!!
