Is my phone still covered with apple care

See especially section 4.1g here.

That certainly sounds like you are no longer covered. (This is a U.S. document, but that provision may well apply elsewhere.)

Was the repair done at an Apple Store or by an Authorized Apple Service Provider?

• Yes. Return there and seek assistance.
• No. You have violated Section 4.1g. Your iPhone is no longer covered. Apple can no longer assist you with this iPhone.
