data entry job scam chandigarh, punjab

It started with a call telling me that I have been selected for some work from home data entry role the girl named herself Tanvi sharma.and she is talking from chandigarh .She asked me to submit some documents for verification and told me that I will be getting a laptop for work from home. then she asked some applications fees as they were providing laptop so it is a security money of 950 . next day I received an another call from her colleague basically her boss she told me that my interview is scheduled and I have to pay 2700 rs for some kind of insurance which will be refunded within 25 min but it didn't .Tanvi was assuring me that it is not a scam and I had to believe her so I just paid everything because I was in geniune search of a job. Then they told me that I will be given a confirmation letter by mail within 10 days . I realised that I have been trapped because my inner gut feeling was strong that something fishy is happening .after some days her boss message mein with one letter with QR code and told me to check if the QR is working or not .The QR code didn't opened and then she asked me to pay 1800 as that QR code is having security to be opened i didn't pay that amount because I was 100 % sure it was a scam . their number are mentioned below tanvi sharma [PHONE] her boss [PHONE]
