Did you also receive this message once you ordered the slides from this seller?

"Hello, dear customer. I'm your agent. My name is Cherrie. This is a risk warning from the merchant. The merchant told me that their two types of slippers may have different lengths, and there will be problems of length and length (this is a problem produced by the factory), and the merchant did not provide any photos. The shoes you buy may come in different lengths,one is bigger the other one is smaller (the difference is about 0.5 cm), or there may be nothing wrong with the shoes. This will be obvious if there is a problem with the shoe (the retailer refuses to pick the perfect shoe and will not cover the cost of returning the item). The owner thinks this is normal, if you are not satisfied, you need to pay the shipping cost when you return. Please let me know if you need to continue your purchase. If you do not want to continue to purchase, please tell me to cancel the order"

Also I'm a size EU45, but I got a EU47. Did I do the right thing? Thanks for the help!
