Disgusting Discovery Bank

This bank is a ****. I had money ****** from my account by a 3rd party. I queried it and nothing happened. I have re tried to quiet and every time the bank says they will get back to me but they don’t. I then wanted to close my account and they told me they would send me a settlement amount but never did. This has happened twice. They do email me and have the correct email as the ticket just get closed on their side and I get email confirmation that I have not responded. They have told me every day that they will phone me to confirm they have sent the settlement figure and I have followed up every day but they keep saying they will phone but never do. This has been going on since the beginning of December. I am now considering legal action. I will never use them again!!!!!!!!
