Natwest charges help!

I need help with Natwest.





Basically me and my wife have the following 4 accounts with them which defaulted in 2013.





Bank Account 1 - overdraft limit was £3000.00 - receiving letters for over £5500.

Bank Account 2 - overdraft limit was £1100.00 - balance know is over £1600.00

Joint Bank account - overdraft limit was £1500 - balance know is over £2200.00

Loan - balance was £450.00 - know is £650.00





My wife suffered depression after a miscarriage so wasn't get paid from work, things spiralled and I buried my head in the sand - I am trying to resolve all these issues know.





I am just wondering is their anyway I can put a complaint in about these charges - over £4000 off those balances are purely charges which NatWest applied on top of charges.





Anyone any suggestions?





Thanks
