Raajnett — no connection for past 1 month

Address:

Chennai, Tamil Nadu, 6000097

We are using raajnet for past one 1 year. Last month they offered new plan if we pay 2870 it means if we pay for 3 months 1 months will be free. So we paid for 3 months but after 10 days raajnet company is sold to other company. But still customer we are not getting connection. Our user id sgr1030 for the past one month there is no connection and they are not attending calls also. We paid for 3 months but we dint use it for even 10 days properly. Please help me to come out from this
