Tata Docomo — not registered with network issue

Address:

560045

Hi,
This is my no [protected] to get the nano/micro sim i went to tata docomo retailer and for replacement he had blocked my sim. Before that he mentioned that will be activated within a day. Since i am using only one mobile number and he gave assurance that will activate within a day, i accepted to block i. E. Only outgoing wont go but incoming could be received.
But still i am facing the same as "not registered on network". I keep on calling that retailer guy but he is not responding properly and his number is: [protected] and he is not checking with the customer care as well.
Kindly take some necessary actions and make my sim mobile number to be work.

Thanks in advance

Regards,
Krishna
