Indraprastha Gas Limited [IGL] — My gas stove burst after IGL connection

Address:

West rohtash nagar , shahdara

We’ve been using LPG cylinder since 20 years. Last week officials from IGL came for png pipeline connection, we insisted him that we don’t want pipeline gas but even after so many request he didn’t listen to us and he stated that this is compulsory, after all that installation the nozzle from stove was making some noise, we told him the same on the same day, but he refused to do anything and said this is how it works, it is normal. Now today, our stove produced a burning smell and within a minute our stove bursted right in front of our face. After this incident we immediately called the person from IGL who installed this mess and now he is not responding even rather than accepting his negligence, he is blaming us for his doing. His name is Sunil ([protected]).
I want an answer from you guys, who’s gonna pay this mess ? Just get me my stove back, i want an answer from you.
