I once bought a moped in Yadea and it broke down for four months. I called Jiaozuo Yadea for after-sales warranty, and they said there was a charge. I asked why, and they said that the bad parts needed to be recharged. I said that the warranty card didn't say wearing parts, and the after-sales staff couldn't answer it, just because they didn't give you money to repair it, they couldn't kill dozens of dollars. This is Yadea, Jiaozuo.
