2nd time in 3 weeks - Debit card *****

This is the 2nd time in 3 weeks - on 1st March monies were taken off my account without authorisation. It was reported - the card was stopped and a new card was picked up on 12th March. On 20th and 21st March the same transaction description went off my account 3 times while I was asleep - the transaction ran into thousands of rands. How is it possible that Nedbank can not pick up these Transactions as ***** when I reported it on 1st March!!! How are these amounts going through without the one time password. This is a new card!! I'm still waiting for the transaction that went off on 1st March to be put back into my account. How many weeks / months will it take for the ***** transaction that went off last night and this morning to get put back into my account??? How did my debit card get compromised when I just got this card! This is ridiculous!!! I've been with Nedbank for 15 years - if this this is not escalated and the monies are not put back into my account within a week - I will change my bank.
