T-Mobile deeply regrets the sorrow the Butler family is experiencing. If we could retrieve this voicemail for the family we absolutely would, but unfortunately that is not possible.
When saving voice mail messages long-term, customers receive an alert and are prompted to resave messages that they’d like to keep. Unfortunately, when the voicemail-to-text feature was added, it applied a shorter window for resaving messages, and the voicemail message was deleted. We sincerely apologize that the Butlers were not adequately made aware of this possibility and are working internally to assure this information is clearly communicated to customers in the future.
Please take steps to save those precious voicemails. http://support.t-mobile.com/docs/DOC-4115
