Hello sabbir360, please see here on how voting bots function. If you wish, estabond can undo the vote and refund you, but please realise that voting bots work on a bidding system, meaning there is no garauntee of profit of a vote, if other people outbid you :-)

All bots clearly display their ROI (see link above) and the bidder has to check everything before deciding to bid. Another method is to bid at the latest time possible before the bidding round is over.

Still, estabond can undo the vote and refund you at this time
