We have one open insurance policy with National Insurance and one road movement is to take place from Teleganag to Bengal. There is an advance payment of premium amount and we would like to notify Insurance Co at week end (due to holidays, there is no dated acknowledgement but regd letter only). My reading is as political unrest is brewing all across Andhra Pradesh, a seperate acknowledgement will save the interest of insured as otherwise a civil disturbance might help Insurance Co to avoid compensation route, in case of any untoward incident. Please advise.
