Went to Tesco this morning and filled up with £49.77 of fuel. Just by chance I was checking my credit card account transactions online and noticed that the £49.77 had been charged twice. I contacted my Credit Card company and thy confirmed that this was the case and that I should contact Tesco for a refund.
I have spoken to them and they are getting back to me.
Do you think I shall be entitled to Double the Difference for being overcharged? : )
I would suggest if you have used Tesco for fuel that you check your credit card. I would have thought they had systems in place to stop you being charged more than once.
