Unable to set alarm

[lorn59]

I have had problems with my alarm recently in that I was unable to switch off the alarm as I have done in the past. The only way I could turn it off was to shut down my phone. Now my alarm wont set at all. I set it as usual and when I click ok it just keeps telling me the alarm is off. Any help will be appreciated thanks. Also is there any way I can do something about the volume on the phone - even set at max its pretty poor. All other phones I have had (mainly Samsung) have been far superior when it comes to ringtones and volume. again thanks for any help. is there anyone out there who can help me please
