The answer is no. If no one knows your account information, your buddy can't receive text messages from your Chikka account. From what it seems, someone hacked your account and I suggest your reset your password. Navigate to the official web page, click the Need help signing in? option and press Do you want to reset your password? button. Type your phone number, click Next and follow the on-screen instructions. For further information, I suggest you use
