TERRIBLE! WORST EXPERIENCE EVER! I had to state my case for 65 minutes on the call for their error of sending me the incorrect item. I called their customer service yesterday afternoon around 2 pm PST, Wednesday, Nov 30th telling the service rep that PetMeds had shipped me the wrong Denamarin package twice in a row. I purchased the blister pack version (as shown on the PetMeds website) and not the bottle version. I wanted an exchange again and explained to her that the bottle version does not work for my dog's case because the bottle version has an expiration time of 4 weeks after opening the bottle. She checked with her manager and found out that PetMeds has only the bottle version. The packaging of Denamarin shown on the PetMeds website was incorrect. [Long story short] She told me to contact the manufacturer directly for my case instead of offering me any quick replacement or refund options. She made me feel like PetMeds' wrongdoing has become my problem. I ended the unpleasant experience with the service rep and requested that I speak with the manager directly. The manager wasn't helpful at the beginning either. The manager eventually decided to give me a full refund after I told her about my disappointment in them not valuing me as a loyal customer for 11+ years, pleading my case for 1 hour, and this was my first complaint. I have to ship the incorrect items back to them too. The whole experience was awful. PetMeds is only nice to you when you give them business, and they become unpleasant when you want them to correct their own errors.I hope my bad feedback won't get anyone fired. I only want to share this bad experience so that PetMeds can correct them moving forward...hopefully.
