Why is MTN so dishonest?

If one tries to phone someone who has an MTN account, and you don't get the person, you get a message "You don't have to leave a message. A voicelike sms will be sent". What absurd bull. The person will in any case get a missed call indication. By no stretch of the imagination can an sms be voicelike. Their use of "voicelike" is insane and only indicates how dishonest this company is. By no stretch of the imagination can an sms be "voicelike" !
