Nasty letter from boi

I recently got a nasty letter from bank stating that because I had missed small repayments on a loan ,(money in account in bank to make repayments but because of some mix up at bank payments were never made on time),I would be recorded with the Credit Bureau ,now since the mistake was banks fault what course of action should I follow .Any suggestions welcome.

Have the bank admitted it was their fault? If so, they have an obligation to correct any information ICB have on you.

If they have not accepted liability, and you are absolutley certain it was their fault and not yours, then call into your branch or write to their credit control department with proof that it was their mix up that led to you missing repayments.

If that doesn`t work, make a complaint to the IFSRA.
