Not good service at all

We are very unhappy with Avbob my father passed away Aug 2021 and after the funeral Avbob let my mom know that she is no longer on the policy we have emailed thru the policy several times where it states incase of the policy holders death the dependent is still covered and she will just not received bonus on the policy. Its now 6 months with no success. they are not answering mails and every time on the phone its someone else that trying to help send mails to client help but no feedback.
