On mar-12th. I was calling the hdfc payzapp care toll free number. The number was busy. Then i search in the google for alternate number. I found this number in the begging.+91-[protected]. They asked my mobile number. Then suddenly he took money from my wallet.
Then i call again to that number stating why you used my money from my wallet. He talking very rude hindi language and telling me to complain in the cyber cell if i have the guts.
Need to take necessary action. When i call the toll free number i waited for 20 min to make the call to speak to the banker. The they sais they are aware of the same. Tole me complain in cyber cell.
