**DO NOT GIVE THIS NUMBER ANY INFO**  Claimed to be Sprint and asked for my PIN to be able to apply a discount for our loyalty. I asked them to verify they were spring and read me the details that they have about my name and address. He provided me with my maiden name and when I asked him to verify the address and other names on the account, he became flustered and asked for my pin again. I let him know that if it truely is a loyalty discount he would not need me to provide any information and could just apply it and I hung up on him.
