Visitors Insurance

Hi I have this very bad experience with Coris America.My father-in-law was diagnosed of blood cancer while he was visiting us.We had to take him to the physician couple of times and get multiple tests done.Coris America said that they will pay for everything.We have sent them all the papers we got from the hospital and the doctor.They say all claims were approved.Its been long 4 months since then.But the hospital has sent us last notice now.Inspite of calling coris people numerous times they still say that payment section is handling it now.Wanted input from people who have had such experience with Coris.As far as I think they are not going to pay and just keep postponing till we get frustrated and quit bugging them.Is it a fraud company?Please email me or let me know if someone has got paid from Coris ever.If so how and how long did it take.Thanks.Your input will be greatly appreciated.One last thing would strongly advise anyone who is planning to buy New India visitor Insurance..Please donot buy it.For what we have gone through in so many months, I would recommend buying an insurance plan from here to have complete peace of mind, eventhough it is slightly expensive.Thanks,LR
