Saks Fifth Avenue review: Horrible customer service

The customer service is horrible - they don't take responsibility of their own mistakes:
1. Order a girl's dress on December 24/ 2024 online and a day later the price dropped by a few dollars, probably by $7-8. I called and was told that I will be issued a credit. They never credited the amount.
2. Ordered another girl's dress online on April 22/23 to be delivered to my granddaughter on her birthday. I verified that the ship to address was correctly set to her address. On April 23rd, I got an email that it has been shipped to my home address - not the ship-to address I had set. I had to ship to to my granddaughter on my own despite having already paid the shipping charges.
3. Called again on April 23rd about both the above issues. After having to state and argue for my case for 15 minutes, I was issued 2 different promotion codes, one for $20 and another for $15.
4. Today on 5/5/25 I tried to use the coupon code but kept getting "Invalid coupon code" message. There were coupon codes anyway on the site for 15% off (e.g. SAVEAPPSF) but codes cannot be combined. I called customer service again and was told - Yes, coupon codes cannot be combines and there are numerous exceptions - coupon codes don't apply to certain brands and items. As I could not find anything useful that didnt have exception, I asked for a dollar amount credit but all they would say is - we are sorry, we cannot do anything else.
