Sunflame Enterprises — Complaint - Service Agent's Threat and Poor Quality Exhaust Pipe

I bought one Sunflame Chimney Misti C 60 model on Feb 14th 2020. While installing it at my home in Gurugram, I called the Sunflame service and one service agent arrived to install the chimney. As there was no wooden plank attached with the wall, the agent asked to attach it first then contact us again. It was told on customer care that 450/- will be the charges however the chimney was not installed still the service agent asked 350/- for a visit and said he will adjust this when the chimney would be installed.

Later lockdown happened and it was not possible to call anyone for the installation. After June, I placed visits for the installation but this same service agent didn't bother to come and asked to cancel those visits because plank was not there, I tried several times to ensure that carpainter and the chimney agent are present at the same time so that the plank would be placed according to the requirement of the chimney. I had carpainter visit twice but this chimney agent cancelled the visit. Yesterday(30th August 2020), I managed to fix the plank on the wall and asked that service agent to install the chimney. While installing he was in a hurry and pulled the silver foil pipe fast, once the chimney was installed he asked for payment of 600/-(450 for installation and 150 for clamp). I wanted to pay 250/- which includes the clamp(150 and 100 rupees balance adjusting for chimney installation paid last visit). I refused to give the full amount due to which he got angry and threatened us that if anything happened to your chimney in future, he will make sure no one will visit our home to fix it. He said, he is the boss of his franchisee and he won't be servicing us in future and not allow anyone else too.

Service agent also said while installing the chimney the pipe will last for atleast for a year however when the pipe broke I called him and he said this pipe is given for display purpose only. If this is the case why was it not informed to me in advance.
Later in the evening when we tried to use the chimney the foil pipe broke into half. I have never expected such a type of service from Sunflame.

I'll provide the required details for this case:

1. Receipt of 350/-
2. Picture of dated 30th August 2020 that chimney was not installed
3. Picture after chimney installation
4. Picture of broken Pipe
