I think my natwest account has been hack/someone may have got into it as i logged in today (online banking) it had a transfer of 100£ to my other account?? i have not made that transfer, so it is looking fishy...
Has it happened to anyone before?
other is a savings account and both are linked
This happens to me all the time. If funds are getting low in my main account, a small amount is normally transferred from my linked First Reserve account to cover direct debits, normally £50 or £100. I dont know if it's an automated system that does it or if its physically done by a Natwest member of staff.
If you are worried, ring your bank and ask what's going on.
