No Data for the 2nd month in a row

i am an mtn contract subscriber, in February i received my 50 minutes, 50 sms but did not receive my 100mb (as per my contract), have spoken to mtn customer care over 8 times and still no resolve, now in march the exact same thing happens, tried calling customer care, waited for 10 minutes with no answer because of high call volumes, i followed voice prompts and emailed my query and up to now no one has got back to me and my query from February is still unresolved.<br> <br> this is pathetic service and yet without fail my account is debited for the full amount!
