Hartz Refused to Acknowledge Problem

I called Hartz today to find out how to help my cat after a bad reaction from their flea drops. While on hold for 10 minutes I clicked on a couple other results from the google search to get their number. One landed me here. The lady at Hartz asked me a million questions and then swore it wasn’t their product. So I asked about all the other people saying they have had similar problems. She blew me off and told me cheerfully to take my cat to a vet. I said I think I better call an attorney instead. She got very cheerful and told me to have a nice day. Really? My cat is sick, I don’t get to have a nice day. Has anyone contact an attorney for a class action lawsuit? I am writing Walmart today to beg them to take this product off the market. I hope others will as well.
