The website stated:

"You Can't Lose With Our 100%,

The seller ignore my all emails and did not honour the refund guarantee request. Consumer has to be careful in dealing with this kind of seller as any of the guarantee given by the seller may be a trap being set to order their product without fulfilling the 100% guarantee refund.
