Tata Docomo — port I am not able to port

Address:

Hi,
I am not able to receive calls and i complained several times but still the same due to this i missed so many important calls only because of this i couldn't receive a call from the bankers for my loan and it got canceled due to not reachable message i don't think docomo will take responsibility of the loss for their poor network or wrong message transferred so
I am planning to port my number [protected] but while trying to send sms i am getting a message like insufficient balance then i reachered twice again loss of money for that but still i am getting the same message and i am not able to port my sim. I request please kindly do needful
