Dear sir,

I had been purchased tandem cooker 3 ltr of rs.1199.00 on 21 jan 19 but i hardly use it and it start giving me trouble from the day one so i return it on 13 march 19 (Return slip no.436862) since i was busy so i was not able to come early in your mall for returning the product. But the store manager said that you haven't use it properly so i can not return it.
so i had to complaint compulsively in consumer forum. My complaint no. 1216495.
kindly take an action towards it as soon as possible.
Thanks and regards.
