Tupperware — worst quality plastic

Address:

Budaun, Uttar Pradesh, 243601

I have purchased the tupperware plastic containers of 1.2L from flipkart, and on its first use i found the product melted inside the microwave within 6 mins which is something ridiculous. If your product is not microwave safe than why you are stamping it on the product that it is microwave safe.
Kindly look into this matter and respond with the proper solution as soon as possible.
