I didn’t know there is a Burberry in Roseville. I’m located in the Bay Area, I learned that each store even in my area has different policies in regarding alterations and even dry cleaning. The SF flagship has no issues in me bringing in my coat for alterations and dry cleaning, while the Valley Fair and Stanford location just tells me to go to xyz place.
I don’t know how much of a trip it is for you, but I would go to the SF flagship on Post St and ask for their help in rectifying the situation including your alterations as stated in the other thread.
