Vodafone India — Deactivate my sim

Address:

Lucknow, Uttar Pradesh

Sir my sim ([protected]) was blocked by puk no.
I told about this to my nearby vodafone care center.. D customer care person said dat she will give new sim in replacement of dat n she filled replacement form n asked me to sign n i signed it... I paid all my postpaid internet plan amount due...
I told her i don't want present net plan n stop my previous internet plan on my vodafone no.... She didn't told me dat she is activating previous postpaid internet plan is on my new number... N on 3nd june i received another bill... I told about this to vodafone care center.. D replacement sim is not activated yet n d new bill is created on what basis.. I haven't used net... I get poor response from vodafone service center.. Is it not there responsibility to tell wht services they r giving on new sim...
I m not going to pay any money as it's not my fault... Kindly deactivate my vodafone sim...
