no data showing on account

i recently did an upgrade and was promised to get R200 airtime plus 500meg data...my airtime shows when i check my balance but no data...each time i phone customer care they tell me it has been loaded....got a few sms's from a wilson sithole confirming data activated but i still don't see it reflecting on my account....they tell me there's a glitch in the system but if that were true then why does data i buy for myself reflect!!! i'm still waiting for this to be resolved since last week.
