Beware of payment options.

My sister used the Gumtree option where someone pays you via Gumtree and then when the money shows in your account Gumtree collects and delivers the item. Unfortunately after she had put her banking details in she noticed money being withdrawn from her account. She was quick enough to move all the money out of her account but the person carried on trying to take smaller amounts out. The banks ***** unit is now looking into this theft.
