Hi, Does anyone have any info on whether the above is possible at all? Thanks in advance

Hi, I have accumulated some relatively large charges from HSBC Business over the last few years, mainly for unauthorised overdrafts. Is it possible to have any of these refunded? I am in quite a bit of financial difficulty at the minute. I dont have any lending on this business account. I would also like to keep the account open, so dont want to do anything to harm that if possible. Thanks for reading! Jamie
