VODACOM - TERRIBLE SERVICE

Im furious with Vodacom, actually Vodacom are sharks. I went on a holiday on the 2nd of Nov 2019 and when I got to my vacation destination place my phone kept on saying that im offline and I wanted to use maps. I called Vodacom on the 2nd of Nov twice and I was told that my phone is fine and that I need to just restart it and everything will be fine, on the 3rd I needed to use maps again and still the same thing when I called them I was told that im on blackberry setting maybe thats the problem. My 1st question was I have been on samsung for almost 10 years how can Vodacom even say that to me when I get billed every month for my phone. On the 4th Im told I dont have my 10 GB anymore because I have used it on downloads. 10 GB I use it through the month all the time and my kids use my phone even more when im home. How can I use 10GB so fast, Im still waiting for Vodacom answers because it takes 72hours to find a problem, in the meantime I must loss my business and they dont even care. I honestly dont think they train their consultants the questions you get asked one would be like "is this person for real". Absolutely unprofessional Vodacom. I think its time to move.
