PetSmart review: Refusal to allow a return

I purchased multiple bags of prescription Royal Canin Multifunction Renal Support and Hydrolyzed Protein dry dog food for my pet due to her Kidney disease and thyroid issues. I purchased multiple bags because there is a shortage of this particular food and it is almost impossible to find. Unfortunately my beloved dog Penny passed away and I still have 9 bags left. All the bags are unopened and have not been used and they don’t expire until 2024. inhaheball the receipts as well. I live 1 hour from the Petsmart #0739 s I called them and spoke to a manager named Jake. Jake had said they normally have a 60 day window to return food. I advised him that my receipts were more than 60 days and were 4 months old and some a little longer. Jake stated that due to the circumstances of the passing of my Penny and the scarcity of the food he will still be able to either give me my money back or a merchant give card for the return. I thanked him and then the next day I drove 1 hour to the petsmart with the food. I spoke with Jake in person and he was assisting me when he referred to another manager. (Unk name). This manager was much less friendly and told me there is nothing he can do. No return and no merchant card. So I drove an hour for nothing. I spend a ton of money on my pets and I will never shop at a petsmart again due to my treatment. Not only did I lose my beloved Penny but now I’m told by a million dollar business that they can’t help me. Terrible customer service. My name is [edited] and I can be reached at [edited] . Thank you.
