Hi. my balance and available balance on my HSBC account is a difference of £42 and i have no idea what this £42 is. My overdraft limit is £600. My account at the minute reads £364.74 and my available balance reads £922.74. it looks as though £42 is coming out of my account. But i have no idea what this £42 is. And i haven't bought/ordered anything for that amount. And when i go into standing orders or direct debits it doesn't list anything worth £42. Just my phone contract and car insurance which is £50/£54. Any ideas? Thanks.
