Hi Edith, We're sorry to hear that. Please reach out to contact@solacebands.com and they will be able to offer you a replacement for the defective band.
“I initially ordered a S for the bright blue and the champagne pink bands (based on the measuring tape provided) but they were too small. Solace promptly replaced the bands with M size. At first it felt too tight but after wearing it for over a day, it fits like a glove. I don't even feel it on my wrist anymore. Outstanding!”
