I'm usng an Iphone and I want to clear my contacts list in WeChat. There are people who want to add me into their list but I don't want to accept them. I don't even know some of them so I wonder why they can access my profile. There are also people in the recommended list that I don't want to add. I have deleted those names from my address book but they still appear in my WeChat. How can I delete their names permanently from my WeChat app? When I tap into their names, I don't see any delete option. I tap on the 3 dots in the upper right hand corner and I don't see any opttion except for 'edit user info' on the alias. Please help. Thanks!
