[Resolved]  Vodafone — Address Change not done

Address:

Pune, Maharashtra

Hi I have applied for an address change to vodafone store at paud road, Pune on 27th Dec 2010 for my number [protected].'
They told me that it will be done in 7 days.
After 7 days I called up customer care and asked the progress about it.
They said not yet they have received a request for address change.
And asked me to check with vodafone store where I submitted the request.
Again I went there and asked it. The lady (Swapnali) went inside and came after 5 mins and said its under process and will be updated by 2morrow(4th Jan 2011).
I told her that it is very important as my bill will be generated on 5th. It has to be updated by 4th only so that I can get my new address on my new bill.She assured me that it will happen by 4th. But nothing has been happened so far.
What should I do now.. Why they are so irresponsible?
Why they are forcing customer to go to other service providers?
Now I may have to wait for 1 more month to get a bill on new address (If they update it)
