Pet Supply Plus

On August 2nd 2019 I went to this store to purchase supplies that included 7 Flea collars that did not work, I returned them to the store for a refund,and drove 59 miles to return the items. The store refused to give me a refund due to the item not being their brand,yet the store states refunds within 30 days,it does not state for store brands only. The 30 day warranty should apply to all products sold at their store.
