Reported ******* and an unsatisfactory verdict by the bank

I reported an incident of ******* that took place on 26/May 2021. My pin code had been compromised and i so reported and that my bank card was ****** and cash withdrawals were made including a transaction where volumes of alcohol were purchased using my card. The bank went on to investigate and concluded based on the information that i had provided that the claim was unsuccesful and case closed. I received a written and telephonic reports to that effect. What puzzles me is the fact that Capitec has only used the information that i provided to dismiss my case without even investigating by looking into my spending patterns and history. The bank just says your card and code were used. Have i ever looking at my account history blown my funds in one day at around the same location, which in this case was around Crown mines? Have i ever looking at my history purchased so much alcohol all it once? Does that then not confirm that there as something irregular? It is my belief that if Capitec makes an effort to investigate my case, a different outcome will be reached. Are Capitec clients not insured somewhat against claims of ******* and ********ity?
