My FNB card was used to transact even after i cancelled my card and i still have not received my money.

I'm writing this email to express my disappointment as I have been treated unfairly by FNB as a customer.

I lost my card and there were so many transactions that were made in my account even after I blocked my account. An investigation was initiated and I was not pleased with the outcome as the charges of the transactions were not taken into account. I'm told that everything a transaction is made from an an account that has zero balance or minus, a charge of R105 is incurred. The money that was brought back is not even half of the money I lost.
