Epic Games needs more competent consultants...

I have been playing Fortnite for some time now, paid for the crew pack on 2 accounts for 12 month now. This month for some reason the subscription kept on declining my card and saying i should contact my bank. Which i did after a Mr Daytona told me that as well. After a lot of calling, emailing etc Mr Daytona from Epic tells me that subscriptions cannot be paid with a debit card...Now obviously im like...***..how is that possible as I have been paying the subscription for 12 months on 2 accounts with my debit card details...He goes even further by telling me that he cannot confirm or deny this (basically telling me im talking ****) Then refers me to a link which tells me which other methods i can use...of which i have none.. Epic games have completely lost my confidence in them or their so called consultants. How in the **** can they tell me they have been taking my money for 12 months and then just like that they want to tell me im lying when saying i have been using my debit card. Details which i might add is saved on their ****ing site.
