We are very sorry to hear that the sticky notes did not perform as expected. We completely understand how disappointing this must be, particularly when you have consistently enjoyed the quality of our products in the past. Sticky notes should adhere reliably to surfaces like walls, glass, or chart paper, and we apologize that this was not the case with your order. Please reach out to our Customer Support team so we can look into this further and help resolve the issue. If your request is urgent and you need an immediate solution, please reach out to our Customer Support team via https://www.vistaprint.com/customer-care/help-center/.
