Hi,
I have purchased fasttag from paytm on 16/feb/2021 for my father in law's vehicle with vehicle number KL 33 K 638. Yesterday i received two SMS as shown below
"Paid Rs 60.0 toll for KL33K638 at Athur on 26 Apr 2021, 07:12 AM. TxnId:[protected]fP.Updated Paytm Bal: Toll Wallet- Rs 190"

"Paid Rs 45.0 toll for KL33K638 at Pondicherry Tindivanam on 26 Apr 2021, 06:31 AM. TxnId: 0177001E[protected].Updated Paytm Bal: Toll Wallet- Rs 145"

I received this while the real vehicle was still at Changanassery, Kottayam, Kerala. After that I have tried to contact the customer care service of Paytm Fasttag many times. In the automated system they said that they will send an sms to my phone number and there will be a link in that through which i can lodge the complaint, but even after trying 3-4 times i did not receive any. Hence i request you to find me a solution for the following issues.

1. There is someone with the same Fastag registered to this Vehicle number.
2. Money is getting deducted from my Fastag account.
I need solution for both, But my primary concern is the first one which i has to be resolved at the earliest.
