Best of luck
, The first thing they said to me was they will get back to me when they have looked into it nothing happened until i phoned them back then they said i was now been charged the UK average price .
Which despite on the invoice it states the price per litre excluding vat which was the price i was emailed the way in which they did their calculations on invoice the total always meant i was been over charged .
I have a BP garage less than 5 minutes from my house i no longer see the point they promise you a good price to start with then because changes in oil prices etc the prices go up .
It was good to have an invoice rather than a small till receipt but the savings can almost be wiped out by the annual card fee in the end i worked out on my usage i was probably saving about £25 a year . Mike
