Email & Phone Harvest from Chinese App Stores

I'm on the hunt for a reliable freelancer who can gather email addresses and phone numbers from specific Chinese app stores. The targeted platforms are:
- Tencent App Store
- 360 Mobile Assistant
- Baidu Mobile Assistant
- Xiaomi
- Wandoujia

The contact details should be delivered in plain text. Please note, I require both email addresses and phone numbers. Experience with data mining and understanding of Chinese app stores would be a big plus.

I am an app developer who had my app on the above app stores. I am seeking the email addresses for developer support of the above app stores, so that I can have a dialogue with them about the performance of my app on their stores
