Stovecraft Ltd — Combo pressure cookers

I have purchased Pigeon Pressure cooker combo from Amazon.
Within weeks both the handles started getting loose after 2-3 uses. I had to constantly tighten them myself.
A year later the bigger cooker handle became so loose that it is jammed and I am unable to tighten it. As a result I can't use it easily.
Also the lid is very tight and difficult to open and shut.
Now the safety valve of the smaller cooker lid needs to be replaced.
I have been looking for an authorised service centre in North Goa, where I live. But there isn't any except one dealer in Mapusa who is not a service centre.
I wish to have a full replacement of these faulty pressure cookers.
Looking forward to hearing from you
