Dear all,
My name is abhiendra singh and using vodafone no. [protected] (Post paid).
I had been talking to vodafone team from last 3 weeks but not getting support.
There was credit limit set by vodafone for my phone no. Was 2500 rs. And they have raised the bill of rs. 18, 943.
They had not given any intimation that my credit limit has crossed and not bared my services.in such case i am asking them what is the logic of credit limit and as per my budget and paying capability i had set my credit limit but seeing bill amount i am not able manage / pay.
They are not understanding my concern and unnecessarily torturing me.
In first week of sep, they stopped my services and forced me to pay min 10, 100rs and seeing no option i paid but they immediately raised my credit limit and giving bill of 18943 rs. And this revision is also without my consent.
They doing as per their wise only.
Need your support and co-operation pls.
