Can I still downgrade to iOS 7?

I have the iPhone 4s. On Friday, I connected my phone to iTunes and Apple updated my phone to iOS 8 without my permission. At first I was okay with it but now I'm mad and sad. My phone is running slow, turns off suddenly and my phone calls cut off. Is there anyway to downgrade still? Is there any program or jailbreak or website to downgrade? Please Help! I'm DESPERATE! If I can't downgrade I will have to buy a new phone.

Ask apple

I updated my iPhone 5s to iOS 8 on the release day of ios 8 and realized that I preferred ios 7. Luckily I downgraded my iPhone before the signing period for iOS 7.1.2 closed. But unfortunately once Apple realized ios 8.0.2 they closed the signing window for iOS 7.1.2
