Capitec bank is just playing games with me and not attending to my matter

Today makes it 2 months since I asked capitec bank to release my money they are holding and 3 months since it was seized. Till date capitec bank is still saying they are still investigating, please can someone tell me how long it takes to investigate a straight forward case? All the documents that they have asked for, I have giving them even added ones that were not requested just to aid them in finalizing the matter faster, I have only gotten one written corresp from them on all this time and that was because I asked for it seen that each time I call or they call after I must have call and left many messages, their story was always changing.. Till date, Mr Julius Okoro who transfered the said money to my acct who also is a capitec bank client has not being contacted, yet CAPETIC bank claim to be investigating the matter, please can someone explain to me, how an investigation can be carried out without interviewing all the players involved in the matter.. This is a high level wickedness and disregard to me its customer... I think it's better I take this to court and claim damagers based on mental and immotional pain that the owner of the money is going thr right now, with a heavy pregnant wife, which has complications...
