Shame full Service

HI: It has now being 2 months and still I am battling with Vodacom to listen to the recording when they promised to increase my Data speed and send me an Ipad and all this will be at no extra cost to me: Olivia and a Mr Martin Brown were supposed to get back to me but never do. So where to from here I don't know: My monthly fees has increased when it was not supposed to and every time I get a phone call from Olivia who promises to come back to me but never does so. Is this customer service NO NO NO NO NO
