PetSmart

My mother passed away I went to petsmart to get a refund on the doggie training they ran my card but I have not received a refund. The manager told me that it takes up to 72 hours
Upon calling back bc a refund was never credited the manager then told me 14 days and it was my bank holding it. I called the bank and they told me they had no record of a refund. I need my money die to having to travel unexpectedly. I have things not clearing the bank. I need my money and nobody will help me. When a redund has been issued i receive it in a day. I am going on a week now and still no refund or record of one at bank. I will never do business with petsmart again because the management does not want to be bothered with my issue I have spent thousands at this store and this is not the extra stress i need.
