Data Top Up not received

With my ADSL I bought Top ups. 10GB for R99 (28-07-2015 12:54) which I received. I then bought another 20GB (28-07-2015 23:27) and the money has been reserved on my account. I have proof of this. After it was reserved the website gave me an error. I then bought another 20GB (29-07-2015 08:12) because I had to phone for about an hour without anyone being able to assist. The error on the website was:<br> <br> Internal Server Error<br> The server encountered an internal error or misconfiguration and was unable to complete your request.<br> Please contact the server administrator, [Email Removed] and inform them of the time the error occurred, and anything you might have done that may have caused the error.<br> More information about this error may be available in the server error log.<br> <br> I emailed and got a message stating the email doesn't exist. Then I emailed [Email Removed] and they told me nothing is wrong and I'm currently using my 20GB. Well that's because I had to buy another top up. So I still paid R149 and didn't receive 20GB. Can someone please assist me with this? Didn't even get my previous R50 DoGaming back after you phoned me to apologize for the bad service
