From cpl of days here many of telling some frauds/cheaters.

Some people telling real.

And some people telling with ego.

Please don't blame others with out proofs.

He/she cheated you means show with proofs.

Blaming other its not good idea.

Ex:If you pay money through bank a/c means show us bank receipt.

Then you can take necessary action him.

So please don't blame others with out reason.
