Realms free trial charging my card 5+ times

I tried getting the free trial of realms for java edition but the card was declined and I got a call from the bank saying that there were 5 attempts made to charge my card different amounts in Stockholm, Sweden. I only tried purchasing it once yet it tried 5 times when it also should have been free, it also did this when I was trying to buy java edition. It charged it 5 times from Stockholm, Sweden and got my card frozen for fraud both times.
