With Maritz I keep the most detailed records. I learned the hard way last year when phone shops that needed corrections did not got through despite several attempts to submit. They did not take or return calls either during that time period. Finally when I did receive a call it was to say, oh well, we reassigned them.I had to get nasty over 5 bonused Shell shops in which the bonus did not appear on my invoices.
On the other hand and times usually I get the corrections made to the bonuses. They do offer the ability to negotiate bonuses. And except for this two week period of time last year they are good about either accepting or returning calls. So in the balance I deferred any action on the loss of income and prefer to keep working for them.
Do not read so much, look about you and think of what you see there.
