A few years ago I noticed a DD on my current account debit card to Netflix, have never subscribed.
Contacted bank who immediately refunded, cancelled card and issued new card, thought that was it.
New card had different 16 digit number as would be expected.
Next month, same again, same DD to Netflix.
Again contacted bank who immediately refunded, cancelled card and issued new (different number)
Believe it or not, next month, same again!
Had enough by now, had a long chat with bank head office.
They admitted they had not or could not contact Netflix and advised me to do so myself while issuing yet another replacement card.
Netflix were very understanding, gave my current debit card number and name and asked if this was as per their records which of course was not, accepted as fraud, and cancelled the subscription, matter finally resolved.
Bank also admitted that card number changes are automatically updated to any company who request this on a DD, the reason why 2 further fraudulent debits were honoured on 2 different cards after the original fraud was reported.
