wake up calls

I have a new landline number and for some reason there is a wake up call set for 5am. I have already called once and the agent could not find it on the account. i had just set up the voice mail. The agent said that should clear out any previous setting. I am still getting these wake up calls and I dont know how to take them off. There is no menu option to delete a wake up call. There is only options to set up wake up calls.. Please help...
