Dear NS team,
I am writing to express my concern regarding a recent charge on my account. One and a half years ago, I cancelled all my subscriptions and services with NS. For the subsequent year, I have received no communication or notification regarding any fees or outstanding payments.
However, I was recently informed that I need to pay a fee of €18.70 (Invoice number: ). I am perplexed as to the origin of this charge, as I have not been using any services that would warrant such a fee.
I request a detailed explanation of the fee and its justification. If this charge is an error, please rectify it immediately. I have always ensured that my account is in good standing, and this unexpected fee is both surprising and concerning.
Thank you for your prompt attention to this matter.
