Fica/KYC requests keeps on coming month after month with incomplete updates

No end to Fica/KYC requests even though it has been submitted multiple times. When do we start giving up. No once again being threatened with account suspension although I have gone through this 4 times in the last 6 months.

I am not sure what more to do, they keep on getting my address and business info incorrect. Does not matter how many times I send them the info, it remains the same. It took them 10 years to change my address, now it has once again been captured incorrectly and every time the ask for Fica I send them all the info just to get another request a month later with the wrong info. it is never going to end. They would rather harass their clients than look into why they keep on getting it wrong. There is not integration between the various departments so you have to submit different forms to each dept i.e homeloan vs transactional accounts vs investment accounts. Each dept asks for the same info, how many more times would I have to submit. I am one client with a business account. If this is so difficult, how difficult is it not for other businesses.
