I ordered three water filters for my Whirlpool refrigerator but received tje wrong filters. When I contacted the company (which I could only do by giving my email address and phone number, since the site does not have a contact number), and it took three business days for the company to respond, which they did by email. I was told that an exchange wasn't recommended, because I would need to pay my own shipping costs and that the product may not be accepted if it not returned in perfect condition (on other words, it might be damaged in transit). I was even toldvthat I could try to resell the filters or give them away. Thisvis definitely notvwilling to work with you, even if the mistake is theirs, and I would definitely reconsider purchasing from them regardless of their prices.
