BSNL Broadband seems to have blocked SSH Port 22 on their network

I am from Kerala and i've tried ssh login and sftp uffff both are not working.
 
Anyway I am going to BSNL office, let me see what they say. I hope they fix it, Here in my HomeTown the BSNL is the best broadband others are not reliable. For now, for SSH I am using mobile boradband connection.
 
I am at BSNL office, initially they told me they cannot block ports like that, but after showing them the exact problem, they are now confirming that they have blocked port 22
