Your sister's account is Tanvi50_? So whose account is
halim50_? You've sent merits to and received merits from that one as well, and I find it extremely hard to believe that a username format like that one would be used by two different accounts
and show up on your merit history.
I think you're a cheater at the very least and probably a blatant liar as well. The whole "blah blah blah a relative" thing has been used so many times by barnacle-sucking scumbags that it raises a red flag in my mind immediately.
I said already, sir. I helped them to learn how to work, and I created those accounts for them. I am ready to provide proof if you want. But i don't know how to do it and what will be accepted.
