An Upset Loyal Customer who is being ********** !!!

I have been using Vodacom for over 15 years and my loyalty is what is costing me right now. I have never experienced what I am experiencing now . In the last 7 days I have spent R900 on my cellphone data , mind you , I am not big on Social media or any other thing. I also pay R998.00 per month for my wifi router and about R300 for my pocket router. Can someone with expertise at Vodacom please explain to me how data worth so much can finish in a month ? I don't want to talk to a call centre person as they knowledge is as good as mine . I know so many people that use other networks and don't spend this much. I have called Vodacom to try upgrade hoping I will spend less and I was told I must pay R600 more, explain to me how I can possibly spend all this money on MONTHLY data? You are ripping me off and the speed at which your data finishes is ridiculous. I again called to rather conclude my relationship with Vodacom, not just mine but my family too and I was told I was told I need to pay R11 000. Vodacom is ridiculous and at this rate you will lose customers instead of gain customers, your competitors aren't ripping people off and you are and this strategy is not going to get you anywhere. Can someone call me so we can arrange how I can pay whatever they want me to pay and migrate to better and user friendly networks. Also this wifi router's network buffers when I connect my phone so I end up switching to mobile data and it works just fine, aren't wifi routers supposed to have network boosters? This is ridiculous!!!
