My boyfriend is in London and he have sent me some gifts via parcel. The link which my boyfriend has given me I am able to track details. Now, my parcel shows to be on hold at chattrapati shivaji international airport. The courier people contacts me by email. Have asked me to send the clearance fee of Rs36000 which I have paid. They gave me an individual account details instead of the account number of company. Now, they are asking for Rs1,19,000 for insurance out of which I have paid Rs28000. They have not provided any receipts to me in spite of me be asking them many times. I don't know what is going on. Is, this a scam? Does any homeward courier exist?
