Mamas & Papas Slumber Swing

we purchased a slumber swing from mamas and papas for our new baby. when we put our baby in this swing for the first time, he did not enjoy it, it was too fast and made him sick and get hiccups. we took this item back to store and they wouldn`t take it back as they said that they would not be able to re sell it.the manager of the store was very rude about the whole situation. there return policy is awfull, and after spending alot in store and then being teated like this. it has made me think about where i shop now, and it won`t be at mamas and papas.
