Find My IPhone

I lost my iPhone and after 4 months have received 4 SMS's telling me that:

1. Find My iPhone. Your lost iPhone has been found to access https://Apple.inc.......... Apple Support
2. [Find My iPhone] Your iCloud "photo stream" information is being restored into the phone of Mr Jack. As this is a remote synchronous operation, you are strongly recommended to timely access https://Apple.inc..... and click the "interception" at the upper right to invalidate this operation if it is not done by you in person. Apple Support.
3. [Find My iPhone] Your Apple ID was signed in iCloud on Berkley L***'s iPhone. If you believe an unauthorised person signed into your account and manage your account by going to https://Apple.inc........ Apple Support
4. Find My iPhone. Your missing iPhone has been found by police nearby and handed over to Apple related department. Your iPhone will be returned by post. Please click https//Apple.inc..... Apple Support

I logged into my iCloud directly, and have changed my password.

I tried the link on a Microsoft PC, error message "Web page not found".

Would Apple send me SMS's as per the above, or is it a scam for a third party to get into my iCloud account, anybody with the low down that could point me in the right direction, it would be appreciated. As much as I would LOVE to get my I6 back, I don't want to lose through a scammer.
