Disney plus promo ****

I signed up for the R49 per month disney plus promotion. The debit order went out fine for two months but this month Disney plus claims to have tried to debit my account 3 times and now canceled my subscription saying that the transactions declined and there was probably no funds available. There was more than enough funds in my account and I now checked with my bank they have confirmed that there is no declined transactions on my transaction history and it would have show if it did decline.
