I got a call from this number and they left no message. I blocked my number and called it back later. No one answered but the message said Leave a message for KIMBERLY with GTS WORLD WIDE. The mailbox said it was full. Have never heard of this company. It's a T-Mobile cell phone number, as the call ended with thank you for using T-Mobile voice mail.
