Hello @afterglow
Thanks so much for coming through. I can't really tell which Of the options I have been a victim. But, with how everything went, though aren't sure, seems to me I have logged into a 3rd party app or website. I haven't logged my account into any one's system or phone either have I downloaded an app away from playstore.
Welcome. And thanks for the response. I asked you those questions so that I can isolate the problem. Can you mention to me the 3rd party where you are looged-in? By the way. Do you have an antivirus on your phone?
No I don't have an antivirus in my phone.
Install an antivirus then scan your phone. What is the 3rd party that you logged in?
