[Resolved]  Flipkart — money transferred for offer claim

Address:

Gautam Buddh Nagar, Uttar Pradesh

I received a call from a female from offer and promotion department of flipkart notifying me that i have won either a laptop/iphone/fridge/tv/ac. And to register for the prize i need to select a product of 4999 and transfer that amount to an account via google pay. I selected the product jbl speaker and transferred 5690 to the account they told me to. Then she connected me to a senior called nitin singh who told me i have to pay gst for the prize and transfer 12999 to the account they tell me to. When i refused to do so and told them i want either an authorisation letter or email or my money back. They told me unless i pay the gst i will not be getting the money back. The number they called me from is [protected]. Account details - ujjivan small finance bank 0842 branch park circus kolkata
