She's 16 and has an account with Santander. Apparently you cannot go overdrawn on it but I beg to differ. This has happened 4 times now. All for amounts less than £10 but they have written to her once saying if it happens again they will close the account. And this week she has done just that. Her apple pay has been suspended for the 2nd time. I only know this as I opened the account on her behalf and used my email so I get the alerts but dd does too through the app. 1st time it was a mistake due to a subscription, 2nd time she miscalculated and it was about £2 so I paid it off but she's done it again twice after several warnings. I don't know how much yet but I'm annoyed after warning her. My worry is if they close the account will this go on her credit rating for the future? If not then I think it's a lesson she needs teaching but obviously I don't want it to affect her in the future.
