Disappearing data!!!

Today at 16:20 I noticed I was out of data. I recharged with 1 GB. I went to gym for about an hour and a half where the gym has wifi (Not that I was using my phone). Got home made dinner and just after 20:00 I couldn't access a website. Checked my balance and it was zero!!! What the hell are you doing Vodacom? *****ing from customers left right and center. This is not the first time I have experienced this!!! I think this is despicable business ethic. What the hell are you doing to get your systems right and how am I going to get my data back? If I could give you 0 stars I would. You're pathetic and a disgrace to anyone who knows a thing about business. I called your call center twice and got cut off after holding for ten minutes due to high call volumes. Because I am probably not the only customer you're *****ing from!
