Vodafone - Mobile numbers not delinking from my family plan

Dear sir,
I have to write with great sadness that I am very upset with the service of Vodafone, due to which I decided to port my all mobile numbers
and also paid all the outstanding dues. After which I requested to delink all the numbers in Vodafone. Then I requested to delink all the numbers in customer care on **.**.****.
And got answers from custom care That your whole number will be delinked in half an hour. After that I tried to UPC code generate several times but always got the answer
was that your code cannot be generated. Even after I did not find a solution and was told that when the next bill is generated, it will be removed. if you are able to give me solution otherwise there is no way left for me.

My complaint reference no. is C**-************, dated **.**.**** & C***-************ dated **.**.****
