BBB Rating

We have been in business for just over 5 years. We became accredited with the BBB, but because of a few complaints (less that 0.5% of our customer base), our rating went from an A+ to a C+...is there any known way to quickly bring up our rating that anyone is aware of? According to the BBB it takes 3 years for the complaint to drop off -- but I have seen our competitors go from a F rating to an A+ rating overnight.



Any thoughts/ideas would be appreciated!
