Meghan Markle's As Ever brand has been forced to issue refunds and promise free replacement jars after overselling its popular apricot spread.
The product, which sold out within an hour of its launch last month, left some customers empty-handed despite successfully placing orders.
As Ever sent emails to affected buyers, stating: "Due to high demand, we are unable to fulfill your order of the apricot spread at this time. We are refunding the purchase of this item by the end of this week."
The company assured disappointed customers that they would be "the first to receive it, free of charge" when stock becomes available.
The ordering glitch has sparked mixed reactions from customers, with some expressing frustration and others urging Meghan to keep their money.
One frustrated buyer wrote: "Just received an email from As Ever, they are unable to fulfill my apricot order but will give me a full refund and a free replacement when it becomes available again. I only have a half a jar of my raspberry spread left. It's war tomorrow!!!"
Another customer complained: "I hope they fix this. At the minimum comms should be out literally on the day instead of waiting for your product for a while and being disappointed."
However, some loyal supporters urged the Duchess to keep their money, with one fan writing: "I don't even want my refund, I just genuinely want Meghan to know she is so loved!"
The apricot spread, which is not technically jam due to its high fruit content, generated significant demand during the brand's recent product drop.
Despite the customer service issues, Meghan has expanded her product line with a new rosé wine. The wine is produced by Fairwinds Estate in Napa Valley, and Meghan reportedly spent months developing the blend.
