VODACOM ******* FOR DATA

I recharged this morning at 9:15 with R12 air time then soon as that was done i dialed *111# and purchased the data for R10 for 100mb which said successful. i then had call 15 minutes later and then got off the phone to go on to my whatsapp to send a message. My messages were not going through so i restarted my phone and still it wasnt going through i then checked my balance at 10:15 and i had no data no airtime left.. 2 minutes later i receive a sms saying technical error please try again by time i received this message all my airtime was already used up which i was not even aware the data was not even through. The agent said tgheirs nothing we can do because it used it for my applications. I think this is really unaceptable because what if i had loaded R100 airtime and was not aware that my data bundle was not even on. this is not first time this has happened to me and all i kept on doing was bying more because i though maybe i did use it up , but this time I refuse to keep quite and let this go because its either vodacom compensates me or i will make it know to everyone of what happened to me because the agent i spoke to had no energy and no willingness to assist.
