There is a competition running at BP filling stations

There is a competition running at BP filling stations. You scan your till slip and send to them. Firstly it was a win a mini Cooper ,then now it's now a R3 000 voucher bundle. A petrol refill of R600 with the first one to win a mini Cooper and R350 for R3000 bundle. This competitions seems like a ****. If it's their marketing strategy it's really dumb. With my latest fill up for R350, then they say the receipt has been used. I resend it again and then they say they will verify the receipt within 7 days. Are you for real BP filling stations? This needs an investigation 🔎 🙄
