Everything. While this company’s products might be viable, their customer service and policies are lacking and even sneaky. Without even opening the box, we had to return a product immediately upon delivery. The company charged a restocking fee… fine. They also made us pay for all the shipping charges back… fine. But they also sneakily kept the upfront costs of shipping that box to us, and after all was said and done we didn’t even get back half of what we had paid for the product. In all they managed to keep around $200! Upon calling, THE ONE GUY (that seems to be their entire customer service department) was unfriendly and definitely smug in standing behind vague policies in order to keep that money. He even sarcastically and sneakily kept trying to spin it that “Fed Ex kept it”. I would never order from Big Frog Supply again. Buy local from a company that cares, understands ‘the cost of doing business’, and can’t hide behind the internet/phone!
