Multiple unauthorized transactions on African bank credit card abd debit card.

On the 22nd of January I placed an order and a transaction of R185,17 went through on my credit card, on the 23rd of January I Was charged again. Went to the app to dispute and I was told to contact my bank as they only charged me once. So I disputed it with African bank pending investigation haven't received my refund. Yesterday on the 1st of April Uber Eats deducted R185,17 again on my African bank Debit card . Looks like they are trying to **** people but why with the same transaction? I feel like African bank is failing when it comes to online transaction, our money is not safe from them. and I want my money back a total of R390.34 Case number: ***.
