Call time

Hi I received a call at 07h15 this morning from your offices I cannot remember the agent that phoned. I advised her by law she not suppose to call clients before 7h30 in the mornings. She advised me that they allow to call from 06h00 in the morning and they have been calling people all the time and nobody complains I told her she must call me after 8 because I'm getting done for work she dropped the call
