Charles P, I suspect your follow up letter informing them you’ve contacted the appropriate regulators will have been swiftly dispatched to their …….
“Let’s tread carefully with this potential trouble maker team”
Like most organizations, level one response’s are dealt with people on minimal wages who couldn’t care less about the company they’re working for, or more likely on behalf of…. The group 1’s !!
Your second letter, now involves those group of people who are paid enough to watch their back, just in case if they handle your concerns incorrectly, someone from above doesn’t come back and bite them in the bum from the 3rd group … Group 2 will reply with gobblely gook, techno mumbo jumbo excuses, whilst cc’ing in group 3. This covers their back, at the same time testing your resolve and checking your intellect on the subject matter your concerned about.
Unless a letter pops into group 3’s in-box from the authorities that matches your references, they might adopt , the going round in circles principal or bribe you off. If a letter does appear , then it’s fire hose time….Investigations into crew actions etc.
If it reaches this stage, your query will be managed by managers totally away from the first two groups, because, even Group 3 doesn’t trust their colleagues to sort it out without causing the business more potential damage.
Anyway, good luck!
