Ask HN: Is there a better way for me to interact with companies

Posting here since this is a community that likes solving problems or (even better) may know of a solution.

I am based in the US (just moved here), and I wonder if there is service (or if I am missing something) that will improve how I currently interact with companies? For example, when I moved apartments, I needed to make contact with all credit card companies, my gas and power, bank (you get the picture) to update my address. If I am lucky, it involves me logging into dozens of sites to update things. If I am unlucky, I need to call them up. In addition, my mail box is constantly filled with special offers and discounts that I don't ask for (some which is actually useful, most is not).

So... hoping someone can point me to a solution where I can manage all this (if it even exists). If it doesn't exist, is someone building something?
