FNB not helpful at all

I am a great customer by any measure - 28 years in, never a problem, private and business accounts. I am totally frustrated by the reality of "How can I help you?" It is just not true. Company executives hide behind thousands of call center operatives whose job seems to absorb abuse and shield the real decision makers from the consequences of their decisions. The call center works badly at best. There is no respect for the value of my time. I have to hold, listen to their sales messages and be transferred from on person to another - each one rendered incapable of independent action. They are happy when they can conclusively quote policy which excuses their lack of action. They are not customer oriented. My main problem is this. My business account was frozen at the end of the month causing me great embarrassment. The reason given was FICA compliance. This was ******* as I had been into the branch to sort this out weeks before. My question, which they refuse to answer is "what procedures is the bank official concerned expected to fulfill before they resort to freezing an account?" On the three occasions my account has been frozen I received no prior warning. My experience suggests the people are too lazy to contact the customer - turn his money off and he will quickly get back to us..... I dealt with a Mahomed Shuaib at their PBC operations and he stonewalled me. When I get time I am changing banks - any recommendations?
