Company shipped me an incorrect filter. They are impossible to reach by phone so I was forced to use their extremely difficult and customer unfriendly third party customer service app. Everything there is check the box for the generic issue. I asked for a refund and a return authorization and gave "incorrect product" as the reason. They not only refused to refund the outbound shipping, they charged me an additional $7.99 for a UPS call tag without my permission, claiming I did not opt out of the call tag charge. They further stated that I should not have used the website for a refund, stating I should have called instead. I tried. It's nearly impossible to get them on the phone. After an hour of hold times on several occasions I was forced to use the online form. When I finally got them on the phone the CSR was rude, arrogant and offensive. He kept talking over me and said it was all my fault. He finally agreed to refund the charges "as a courtesy". When I complained about his attitude he said "I gave you a refund, not what more do you want" and he hung up on me. This company is only interested in a sale. Otherwise they want nothing to do with their customers. Buy from them at your own risk.
