Hongkong & Shanghai Banking Corporation [Hsbc] — Fake email regarding fund transfer

Sir we are from Chennai, Tamilnadu, India. We got an email from Mrs.Agnes Edna Dolby that she is willing to open a charitable trust in India and we replied for that mail after a week we got an email from Mr.Noel Quinn and he sent a form of ATM MASTER CARD. Then after a week I got a call from Mr.Steve Boris to pay Rs:15, 500/- INR for courier charges and we paid that after two days I got a call from a lady from HSBC Bank quarters Delhi and she said us to pay Rs:48, 999/- INR for registeration fee and we paid that amount also. Now they are saying that they sent the parcel to RBI in Delhi and I got an email again to pay Rs:86, 890/- INR for conversion of pounds into indian currency but we not yet paid. Is this fake or true? Please try to help me to get back the money which I paid before.
