Insurance claim on loan

Once again after 3 months of waiting for insurance claim with numerous calls and in and out of bank over 10 times submitting documents 3 times..to just receive a email from the complaints manager stating that I need to resubmit documents again and then it will be another how long to wait to reply for that when I have been already waiting 3 months just to tell me once again i need to submit documents before applying for claim. And stating this needs to be done every month so I app**** for claim 3 months ago just to get an email saying I need to resubmit forms that I have done 3 times... Its just going in circles from June now iam frustrated and giving 2 days or getting anbotsman out as this is not getting resolved but they quick enough to take a person's money were i have been a loyal payer for two years now
