@Burak you cannot remove it but you can turn on extended absence.
- Call voicemail and log in with your PIN.
- press 3 (manage greetings),
- then 4 (manage extended absence greeting),
- then 2 (record a new extended absence greeeting) and record a message that indicates to your caller you are not accepting messages.
- Then press 4 to enable extended absence
- Last, , press 5 to dissallow anyone to leave you a message. Problem solved!
