Flipkart — Flipkart cancelled my order without any email or information

Address:

Shridhar mishra, Bank colony , pandit ji road , HAZARIBAG, Jharkhand

I had recently purchased a laptop and a phone on flipkart using credit card and the order was successfully placed and the amount got deducted .
After 2 or 3 days of placing the order on 25 january 2021 they cancelled my order without informing me .
They provided us a refund but what would i do with that, i needed a laptop because i have to attend online classes and for my work like coding and projects.
But now its getting worst day by day as i cant attend my classes properly and cant practice coding without a laptop.
So i request to the concerned authorities to help me in getting my laptop.
Thank you
Dharmesh Kumar
