Dont go with Ditto or anybody else who dont have a physical office in the city where your parents are putting up.
These buggers keep selling insurances like crazy. When you'll think of using it, they will reject the claim due to some xyz reason, wont pick your calls and not entertain you.
Bonus point - every insurance company has 2 different numbers to call
1- customer care for buying policy
2- customer care when u actually try intimate them at the time of emergency. Always call on 2nd to check if they pick your in time when you are in an emergency. Chances are, you will keep waiting for 30+ minutes to even reach them to tell them that your family member is hospitalized and claim process has to be initiated.
Best one's are sarkari insurances only.
They do have some drawbacks but they are far better than the private one's.
Buy your parents a policy and continue with it from sarkari company.
Dont stop it coz if if you buy later on, premiums will become too costly as the parents age increases.
Claim the premium you pay for your parents under Old Regime.
