Hi Alasdair
Thank you for taking the time to share your feedback. We have did some reseach on the nano tape and we found that it is not fit for the textile surface like tapestries. We will include this product finding to our product description.
During checkout, we offer various shipping options, and your order was shipped via surface shipping, which can take a bit longer as it is designed to be more cost-effective by utilizing ships for transportation.
We also want to express our heartfelt apologies for your experience with our customer service. It's disheartening to hear that it did not meet your expectations. We are committed to improving our communication and will be reviewing this internally to ensure that we provide the supportive and helpful service you deserve. Thank you for your understanding.
With ♡ + respect,
Isabella Lee
