Sistema Sistema Shyam Teleservices Ltd (MTS) — MTS Port is Blocked

Address:

Begusarai, Bihar

I am planning to port my mobile no ([protected]) to other network. Every time I am sending message port [protected] to 1900, it is saying either message can't be send or in case it is sent than message cannot be delivered. Talking to customer care they are saying you wait for next 24 hrs then tell us & things going on same.
Same thing happened to us previously also. My brother staying in Delhi tried to port from mts to other network , same problem was there. After All he had to quarrel with mts person then they send the port no.
This company is making fraud to customers.
By this way customer able to reach authorised person are OK & illiterate / Unable person has to compromise.

Its my feeling that they had blocked 1900 no so no one can port their no to other network.
