Vodafone India — csr closing issues without solving it - not getting otp and sms not even changing port

Address:

560103

I am not getting sms and otp for few months now not even from vodafone site. When i raised complaint they closed it without checking it.
Now i have raised a request for port change. They told i will be receiving the port code within 24 days. 3 days later when i called csr they asked why you are changing port? If you are not getting sms or otp that is not vodafone issue. That is issue with third parties. Then they asked me to raise the request sms again. Every time i call they ask me the same thing not even agreeing there is issue with i not receiving sms or otp.
