Constant Disapppointment with BP

where do i start. in the past week, i have visited BP Alrode to find they have no fuel. today, the 9th November, i spoke to the manager who could only show me the shipping reports and explain how petrol is ordered. this is inexcusable. how on earth does a corporation the size of BP not know how to forecast enough petrol as to not run out. there is no shortage, there is no petrol issues in South Africa, so this is a human error, AGAIN leaving consumers scattering to find another fuel depot. further to this, i use BP for the benefits to Discovery. how am i to claim these lost benefits (now x 2) when this is the nearest BP in the area. this isn't the first issue i have had with BP so please,sort this s&#t out once and for all. you keep saying you will fix things, so how about you do that.
