If you are not satisfied, then a letter to the editor is the
best solution. Any editor who receives letters from dis-satisfied
readers in large numbers will certainly not ignore them.

Such letter writers likely represent ten other unhappy readers.
Most people will just stop buying the product and buy from
the competition. And not bother complaining, as they figure
that it would just be a waste of time. So an editor who
gets unhappy letters from 5% of his readership should know that
it means that another 50% are also unhappy. Or make that a
smaller number, as they probably no longer read the mag. But
add them back in if the editor wants to fix the problem.
