Bad Bad service

After passing of my family on 31 Jan my life hel. I made arrangements with debit orders 2 months down the line they haven't correct all our debit orders. We called about 40 calls 20 emails all for nothing. Complaints don't help so what now. We was " Private Banking Clients" such a joke. Yesterday again withdraw car loan from wrong account send request 3 times and they assured me its correct. Our life cover didnt go off. Customer service said here I saw you phoned and request on 18 of Feb. Sorry it wasn't actioned..
