Vi — SMS Spamming

Vi [earlier vodafone] has been spamming my mobile number with pack reminder messages and incorrect SMS saying my pack has expired even after renewing pack and sending multiple promotional SMS from VX-IMPMSG header about their whatsapp support.

many info SMS being sent from VX-ViCARE

They are misusing SMS service under disguise of care.
Inspite of fully registered under DND, airtel itself is spamming.
Multiple reminders for pack renewals, pack expiry etc
one SMS one can understand.

Messages received from other headers also like VX-VOLTE

DND complaints registered are resolved sayinf these are service SMS
When no service is requested, why is Vi spamming customers
