I placed an order and then subsequently found a discount code that provided free shipping (i rebuilt the exact same order in my cart to confirm it worked). I called customer service and asked them to add this discount code, and they stated the only way to add the code was to cancel my order so i could replace it with the desired discount code. I followed their guidance, had the order cancelled, and then prepared the same order. During the customer service call, i mentioned the discount code i was wanted to use was “LSA”. After ending the call, i immediately recreated my order (within 3 mins), but realized the discount code no longer worked. I called customer service again, and they stated they would not honor the code or provide free shipping even though the code previously worked for me before notifying customer service of the code i wanted to use. Instead of honoring $11 of free shipping to a customer who patiently followed conflicting instructions provided by their customer service agents, PSA NOW LOST THIS ORDER AND ANY FUTURE ORDERS FROM ME AND EVERYONE ELSE IN MY HOUSEHOLD. Up until now, i trusted PSA for fair pricing and reliable customer service but this experience lost my trust. I will take my business elsewhere. To provide context, i manage a worldwide “voice of the customer” program for Amazon. I fully understand what it takes to earn and maintain the hard earned trust of customers and i have reasonable expectations. PSA team - if you follow up with me and make this right, i will consider updating my review.
