The worst Bank ever

I had cash depositesd into my acc from car tracker which they hold and l am struggling to get them release the funds. I have since provided with them the proof for source of income. and on top of that they can as well see that money came from car tracker but ever since they are not reachable and making me run up and down and if they ever return your emails they keep referring you to the next person. I regret banking with them and be warned, they do not return calls when you call the call center
