BP are fooling people with their competitions

I have been filling up at BP the whole month of June to get the collectable car for my son. I only got my code on Saturday as I filled up my last tank on Friday. Only to be told now when I tried to collect the car that the competition is over. What a *******. It's only the 1st???? I filled up during the competition, it's not my fault you take 24 hours to send the code. What about those who filled up on Sunday on the last day of the competition and only got their codes today. This is not on BP. Never falling for this BS again, you are fooling people.
