I got double paid for each month. What's wrong with this? I have compared this payment history with the travel history invoice from the NS website. Please can you help me? It seems that I paid twice a month since December 2022 and it keeps running until now. I have made a list of the amount of money that I should not be charged:
1. 20 December 2021: 48,91
2. 19 January 2022: 39,34
3. 17 February 2022: 75,13: I have refunded this money
4. 17 March 2022: 58,05
5. 21 April 2022: 65,15
6. 19 May 2022: 68,75
7. 17 June: 71,79
NS should pay me back for the amount of money that I should not be charged.
