Paytm Mobile Solutions — breach in confidentiality (order details, cart item etc.)

Address:	560045
Website:	paytm.com

This is a complaint against indiashopee.com & paytm.com. I get a call from an executive at 11:30 am on 11/12/2017, claiming that she is from paytm on my registered mobile number. She then went ahead telling that i am listed as one of the top 10 lucky customers of paytm as i purchased one desktop on so and so date. She also tells me all the patytm details and my cart items with all purchase history to make sure she is the customer executive of paytm. Now, she added telling that i have four options as gift items from which i must select one and must go through a minimum purchase of 3000 in paytm before 12 pm on 11th of this month. She says to add item to cart and give her a call on the same number. As mentioned, she had all my paytm details, i went on believing her and did as directed.

I added a ups (Value: 4963) to my cart and gave a call. She tells to make the payment to a number ([protected], wallet tx id: [protected]). When asked why make payment to a number and not payment gateway, she tell that it is a call from paytm gift department so i must go the same way.

Now, after transaction i get a call saying that i will receive the product within 2 days with my gift free of cost and booking details in mail and sms with cashback within 24 hrs. I didn't get any cashback and mail but got one sms (From: [protected] on 11 dec at 1:00 pm stating booking id: sn0847596).

After 2 days, again i made a call to the same number for the status of my order. They then tell that it will for sure reach within 2 days as it was delayed due to some courier problems. After 2 days, again i am getting a call (From: [protected]) saying that they will be charging some 6700 in the name of gst which was never mentioned before. I then tell them weather you cancel my order of give my product without any further payments as i was never aware of this payment to be made. Then they tell that they are from gst team and cannot do the same.

I then called the previous numbers and asked the same, then they transfer my call to some senior executive. When mentioning about paytm, he told that they are not from paytm, but from indiashopee and cuts the call. They then don't receive any further calls and switch of their mobile or put on block.

All recordings preserved.
Some of the executive’s names are as follows: vani, rohan, divyanka
Some of the phone numbers as follows:

Note:
1) if this is a fraud, how can someone access a paytm account and get to know all the details.
2) how can paytm site have such a flaw?
3) how did the transition from paytm to indiashopee took place?
