Worst service ever

In super frustrated and angry with FNB. I need someone senior to call me urgently, i called you last week and i was promised that someone will investigate my matter and call me back. No one has called me back, today i called you in the morning and got a terrible stinky service from MPHO MOSHANE who has put me on hold for more than 30 minutes and was denied to speak to a team leader, he said someone will call me and guess what it's 12h30 no one has called, i called you back again and i have been out on hold for more than 21 minutes by Mabotlela, worst customer service ever. I want all my accounts cancelled with FNB i will move to a better bank. My policy number FI ********** .
