Bad customer service

Was treated unfairly by Old mutual money account after was ****** at the local texi rank in Site C where I lost my new card wich I opened on the previous day right after my pay day because my old card was about to expire. On the 27 July i was ****** money went out on my account from Makhaza Atm, two 2000 was taken buy the ******s who used the temporary pin they got from the letter of my new card. Later in the Day I manage to get a fown n inserted discard into my fown to check my balance on to found I was only left with 4200 in my account and I manage to transfer it to my friends account who was also using old mutual money account the following week I went to the branch to open the new card again when I told them the story they said I can open case of ***** then when I went again to do the follow up they said I dont have a case coz y it took to long to report it and maybe I'm trying my luck I was never ******.My question to them how did it happen on a very same day when u was ****** u gave access of two pins in the same account and their response was it's normal even though i have told them I'm only using 1 pin both for atm withdrawal and cellphone banking and on the following I then went I again follwing week to show then day I received money for incentive but the ******s again took it then the lady assisted who then tryed and call money account looking for answers but still nothing was solved and I was forced to change my account details to Nedbank because my salary I was getting through them.
