Query: Phone locked on a carrier other than advertised and can't be unlocked

The positive: The phone came in an apple box, it was wrapped in apple plastic, it looked brand new and came with charger and cable and turned on. However, the Amazon Headline read that it was previously an AT&T phone. However, the phone was locked and AT&T they have no record of the phone IMEI # every being one that they sold. After spending many hours on the phone with AT&T, Apple, Sprint, Boost Mobile, I finally discovered the phone was previously a Consumer Cellular phone and Consumer Cellular will NOT unlock the phone because only the person who originally bought the phone from Consumer Cellular can call and request it to have it unlocked. So, unless you're a Consumer Cellular customer, this phone will NOT work on any other carrier, ever and is worth NOTHING to me. I have NEVER given a rating below 4 stars on any review I have written. This phone will be returned for a refund.
