No fuel receipt, paid with Mastercard

At the end of December, on my way to a training course, I filled up my car at a petrol station to the side of the motorway. No receipt came out of the payment terminal (the paper had run out) and I paid with my Mastercard. My Mastercard monthly statement only states ‘Esso Drongen Noord’ and the amount, but no mention of the fuel and the number of litres. How can I enter this in Dexxter, or is that not possible and will I lose those expenses, meaning I will have to pay more tax (because my profit in Dexxter will then be higher than the actual situation)?
