Vox And Cell C disappointment

I spend R1500 with vox on data per month. The one day i needed them to credit my data. I buy 10GB and still nothing so i use my credit card for another 10GB, still nothing. Call them 4 times with promises of the tech department will get back to me and nothing. After me missing my match. They do eventually credit my account 20 hours later. Today i watch 6 hours of TV and my 20GB are gone. Cell C is their network and they messed up big time. Goodbye Vox and Cell C. Please do not use Cell C or Vox for your data. You will tear your hair out.
