Harassing phone calls

Banks are pulling out all the stops in this war of attrition. They must've made some strategic decisions based on their human relations research. They must know that people react in certain ways to harassing phone calls. Anyway the banks have been robo calling me. They want to inform me they have special deals, they want to inform me the bill payment date is coming up, they want to inform me how much I owe. Constantly. When I try to talk to a human I am given a number to call during weekday business hours while these robo calls are every 4 hours over the weekend. They are probably within the law but they must be playing a psychological war game of wearing down resistance or something like that.
Maybe they know that any name recognition is good whatever the reason. Humans are probably drawn to the bank that calls them the most. As in the case of celebrities, good publicity or bad publicity both provide the same name recognition. Of course since I am not an automaton I will clear my accounts and change my number but I am sure they will spend their billions to find my new number and harass me some more. This is the battlefield of wall street.
