Bharat Sanchar Nigam [BSNL] — broadband disconnected even after we paid the bill

Address:

BSNL Exchange Ayyappankavu, Ernakulam, Kerala, 682018

We've paid the b. S. N. L. Bill of february 2019, but the next bill of march included the february months bill. So we paid only march months bill. But bsnl staff disconnected our broadband, claiming we didn't paid the bill for 2 months.

I've attached the bill photographs here with. I did contacted the bsnl xchange, customer care. Issue not resolved yet.
