Address:

Patanjali Stores line ,Lakshmiipuram colony , Shivas Enclave, Brindavan colony , Kapra , Secunderabad , Telangana - 500062

I have booked a cylinder on 28th Mar 2021 and got a confirmatory message of the same promptly . i was to get the cylinder delivery on the same day but did not get the same . On 29th Mar 2021, I GET A MESSAGE STATING THAT MY CYLINDER IS DELIVERED where as the cylinder was not delivered to me .
I called the agency, M/S ENNAR GAS, the concerned manager( RIAZ AHMED KHAN ) was so rude and reckless in answering and was stating that " your cylinder was delivered to somebody else" . the delivery boy( IMRAN) had called me soon and was stating " i called you and you asked me to come tomorrow ". Shockingly no one called me and i have a proof of the call records .
This is a regular phenomenon with M/S ENNAR GAS AGENCY and i have been witnessing the same for 8+ years now . the agency is very irresponsible and are very rude to customers and are very poor in service delivery . they are very good in collecting money via delivery boys and in selling cylinders to unauthorized persons ( you may pl confirm through your vigilance wing ) . I request you to kindly intervene and consider cancelling the licence of this person and may grant it to some sensible person who runs it with the sanctity and decorum of IOCL .
