I stopped doing the car negotiation shops after a bonus issue. I was called and verbally asked to accept the two more negotiations shops, with bonus. I said yes. The scheduler did NOT attach the bonuses to the shops. When I sent an email, showing that there was a bonus being offered on both shops, it was ignored. I thought ya know, if you are going to be like that, then forget it. I did complete the two shops and submitted because I had verbally agreed to do the work and I do my best to keep my word. After that, and with no acknowledgement or response regarding the bonuses not paid, I have turned down every single request to do these shops.
I am sorry that you are having such rough time with the company regarding the shops.
Something that helped me when I did the shops - I claimed my son or my brother was an accountant or a CPA and told me to specifically ask for x, y, or z. I said I have no idea what that means, but I am suppose to give it to him to look at with the all the numbers. That worked really well for me! And the guy in charge of the program was happy that he received the stuff he required.
