unreliable service

i app**** for a policy around june,i was told to cover upto ten people under the policy.5 above 21 and 5 below 21 after a month i had a call from one of their consultent and say one of my covered member is not covered due to his age which is what i dont understand coz at the 1st place when,i signed to the policy there were no age limit. yesterday i got another call from one of their consultent,after i send them an email since i wanted to replace the members whom they said he could not be covered under my policy. and thy told me that,there are still more members in the same who are not covered. i had to pull out of the policy due to unreliable service.
