As i am interested to start escrow services so that i purchased an member account.
No one is going to use an escrow of a member account. If that was your only reason you wasted your money.
It's a neutral rating, only giving someone information on how the account was sold. Even if this were a negative rating, it wouldn't matter as it is not trusted feedback. Stop complaining.
Please let me know did i done any mistake here ??
Apart from thinking that having a member account makes you more trustworthy, you haven't made one. Buying accounts is basically the norm here now, sadly.
