Family Dollar

My wife brought some items at the store after she pay for her items she told the cashier to hold her bags because she had to do some shopping so when she finish the cashier gave her bags to someone else so we will like a full refund this is the second time this has happened to us we love shopping there but for some reason this has happened the cashier said that she must have gave our bags away by accident and if we contact corporate office they will refund our money we paid with a credit card,
