As explained earlier in the chat thread email is not the quickest way to get a response as they get bombarded by so many emails that it can take time for them to process them and get back to you. Sometimes they may need to refer things on to the engineering team which can often require an email or two. Its also worth noting that they are based in China and Chinese is their native language so they most likely also have to translate some emails to fully understand them and as we all know some translations can often put words in the incorrect order etc. so that can also add to the delays. I know its not ideal but just wanted to give a little context as to what the delays are for.
In terms of contact routes and opening hours here is the information I have been given…
