I have been battling back and forth with Macy's since our wedding. Here is the story I'll CN at the end.
No one purchased our All Clad 10 piece cooking set. (Pots, Pans and Skillets) The package retails for $600some, so I wasn't surprised. We ended up getting some gift cards and with our coupons and perks with my Macy's CC and waiting until they went on sale, we got them for $100 out of pocket. Plus a free $100 lasagna pan. SCORE.
When it came time to give a shipping address, I gave our new one since I was going down for an interview and was quoted 2 days shipping time. Well turns out it took longer than 5 days to get them and I had to come back to Minnesota. Our new apartment doesn't sign for packages and UPS only holds them for 5 days at their holding center then returns it back to Macy's. I caught it before it made it back to the Macy's warehouse, the sales rep was going to have their manager just replace the order and have them shipped to my Minnesota address. She said to call back Monday, gave me her ext. and blah blah. Well her line was busy almost all day monday so I called the reg line. They told me the Warehouse sent me back the GCs so they can replace the order I'll just have to wait until I get the credit and repurchase it myself.
Kid you not on Wes, the nice UPS guy comes knocking on my door with our pots and pans. I was pumped, however confused. So today imagine my surprise when I get a $400 GC in the mail from Macy's for my "return". I felt like I was playing monopoly. Macy's error in my favor collect $400.

Although it would be wrong to keep it, so I called them to let them know about the error.
I got the RUDEST customer service rep ever! She grunted and sighed as I gave her my info, order numbers etc. Put me on hold for 20 mins. She came back and said we canceled the GC. No thank you for giving us our $400 back because of this cluster, NOTHING. I am bummed they didn't even care. Granted $400 in the scheme of Macy's isn't that big of a deal, but sh!t I could have went a pretty d@mn nice shopping spree. Especially since I am unemployed now.
CN: Macy's error in my favor they gave me $400 I didn't deserve. I called to return it and they were mega rude that I was wasting their time. In the end they took back the money with no Thank You
