I bought a pair of shoes on a Taobao live broadcast the day before yesterday. The seller said that the cowhide page was covered with the first layer of cowhide and pigskin insoles, which was a false propaganda map. There are two ways: one is that you ask the seller to provide proof of the material of the shoes, and the other is that you take the shoes to a professional institution for inspection. If the inspection is not genuine cowhide, you can complain to Taobao clerk. Generally speaking, sellers have no right to blacklist you. You can complain.
