Vodacom sucks

Please can someone assist. i bought a gig of data at about 4am 1 november, the afternoon of the 1st i still had 700mb. at 12am i went to go but more data, and ALL my airtime was used....

I NEVER RECEIVED ANY sms about the data running low. or that it was using out of bundle rates. WHICH i though Vodacom did away with.... stopped automatically..

Please can some one refund my airtime as this is a vodacom issue of the sms's not coming through....

I received all the out of bundle sms's at 2h30 this morning.i still have not received any sms for the the data usage...

I would like my airtime refunded ASAP...
