Hp Gas — not able to reach customer care

Hi, my name is rahul. I was trying to connect with hp gas customer care through phone[protected]. Even if i choose english as my preferred language also it's connecting to some other regional languages which i don't know. Please help me with how to reach out to the hp customer care direct to the person who can speak in english.

My query: i have surrendered my hp gas connection 2 years back, now i lost the paper which agency gave to me. I enquired with another agency and they told without that letter there is no way to renew the connection.in this situation, what is the way to new the connection without the surrender letter from the previous agency?
