Vodafone — flash message in customer care

Address:

Lucknow, Uttar Pradesh

hi Sir,
kindly tell vodafone to stop all FLASH masseges on my mobile no.[protected],as they send every 30 sec one flash msg, to subscribe this or that ringtones or there products, and if i touched any key from my mobile they cut Rs 30-40 form balance , i even activated DND but of no use.
Secondly i tried to call custmer care 121, but never get chance to talk any person from voda, as CC always speaks recorded msg---- you r not alowed to call custmer care.
kindly do the needfull.
