Costing me my business

I have had the worst experience with Vodacom and I have been trying to sort this out in a civil matter, but it seems like they just don't respond. My first problem was I got upgraded to a package that I did not approve. After months of complaining and stating my story and trying to get it sorted. My phone got switched off. I have been in contact with numerous staff members, managers, even trying to contact the CEO. And it has been no joy! I get promised that managers will phone me back I also get promised that my phone will be active again and nothing happens. My phone is the way I generate business, they have been costing me my income. The worst part is. I have been buying data for another Vodacom sim (So I am still paying them) just so that I can use my phone for Data. Your clients is suppose to be the most important assist to you but you treat us like trash!
