Hi,

Hathaway brodband account no. [protected]. Ayappa Nagar, KR puram Bangalore.
On 06-Apr-2019 Saturday there was blast happened to Hathaway modem through LAN cable socket at my laptop. That time I have seen fire at my laptop LAN cable socket point.
After that I am not able to start my laptop. Same day I called to customer care. Two people came and they said there was issue at other end that they were looking and they did not come back with any update. I can see burnt mark on modem socket as well my laptop socket.

Please suggest what further action I can initiate to set right. I need only tow things 1. Modem should work and 2. Laptop should work

Thanks,
