On Jan 4th, I topped up for 15 euro through the Tesco Mobile iOS app. The payment returned an error. I checked that my balance had not updated (it had not) , and topped up again. This second 15 transaction did not return an error.
However, my credit has not been updated (it still shows 0.17) and I see from my bank that 15 euro has been taken from my account twice. Can you help to fix this, please?
