Bharat Sanchar Nigam [BSNL] — problem with ported sim

Address:

Cachar, Assam, 788001

Sir,
this is lokesh from silchar (assam), its been already 6 months that I have ported out my number from Vodafone network to bsnl network. since than I am unable to send or receive sms (text message), I had even complained it to the customer care several times, every time they close the complaint saying that it is resolved, but still I am facing the same issue.

I even visited there franchise office in person. they always write down my number and ask me to leave saying that this has to resolve it from culcutta, but still no update for the same

So its a humble request from my side, kindly help me to solve this

Thank you
Lokesh Kumar Jain
