BP Promises and does not deliver

Why have promotions if you can't fulfil them. Every garage you get to is waiting for the collectible cars. My son is one for detail and he is short of one car. I have three codes, but no one has cars. All they say is we are waiting for BP head office. Well now i am fed-up. I stopped purchasing BP fuel and i have also stopped my companies' vehicles from adding any fuel at any BP.......****** pathetic.
