Hello. I have just installed Facebook messenger on my iPhone 5s, and I have a problem. I saw contacts that I don't have on my iPhone and on my Facebook page too. Maybe I had these contacts on my android phone. But I don't know how to delete them. I reinstalled the app but it didn't help. What can I do? I couldn't find anything in the Internet about my problem. I tried to delete imported contacts but it didn't help also if you know how to delete these contacts please answer. thanks. I forgot to say, that iPhone says that these contacts are from my phone. But I don't have them on my iPhone.
