DELAYING REFUND!!!!

on 29 December 2015 I went to the total to fill my tank. I was advised by the attendant that that I had to swipe indoor as the outdoor machine was faulty. The attendant inside swiped my card in their speed point an it declined. So I withdrew from the atm inside and paid. on my way home i received an sms from my bank confirming that money was reserved to pay Total. I then went back to the store on the 30th and spoke to the manageress Annalisa. She took down my banking details and contact number and said it would take 48 hours for a refund . I returned on the 2nd Jan 2016 and she said her system was down and therefore the I must be patient. I then returned on the 8th of January and Annnalisa gave me the same excuse of her system not working. I am EXTREMELY disappointed by this service as it is not my fault her speedpoint and system are down. She is not helpful and full of excuses.
