Standard bank-*****

My late husband had a cheque account with standard bank The account has an ar accidental death benefit. I lost my husband on car accident in February. Thus bank has been taking me from pillar to post to payout the R 20 000.00 benefit. I've submitted everything that they requested me to submit and they said they come back to me within 45 days. It's been 60 days and now they don't respond to my emails. I'll be taking this to every social media platform to expose their lie benefits.
