Hdfc-ergo

Hi all , recently my father has been asked to get root canal . I have alredy purchased health policy from hdfc. Now when i want to know whether they are going to cover it or not they are giving me vauge answer. They asked me to send mail with proof that doc recommed for treatment . I hv sent it but till now no reply. This people give you 5 calls in half hr to buy health insu. But now they dont even reply on mail for claims 🥲🥲
