Mm Telecom Pvt Ltd — Amount has been debuted asking for refund not responding

I purchased a product from a company named MM
Telecom Pvt Ltd (Noida based company). I ordered a phone from them with the payment of rs40, 000, after I
recieved the product when I unboxed it infront of the company personnel over video call the
product wasn't the product which I ordered for. I have the recorded video of the unboxing as well
as the company has the same too. Now the company is making me go round and round to avail
my return/replacement/refund. They are trying to avoid my calls and texts when I ask them about
any update of the same
