Groupon mall scammed me
They first started with small amount and atlast they scammed into large amount.Atleast they are not refunding the amount which I have invested.they are using students mentality and making scam and frauds.Eating people’s money. They will ask for amount they will unfreeze the item.mostly they are frozen the items and asking for money.By this they are taking all over the amount eating it,enjoying it,and making fun of people’s money
