Capitec bank is ignoring my calls concerning my case

My case number with capitec bank is ***2, it's being handed by Miss/Mrs Sinazo Mbaliswana, a compliant management officer. She did send me an email last week regarding my case and in thst email, it shows clearly that capitec bank is not doing any investigation on my matter, but only acting on the report from absa Bank.. In the email they stated that an absa client who fell victim to an account change **** transfered money into a capitec client account who thereafter transfered money to me.. This statement is totally untrue, because Mr Okoro who sent me the money has said he never received any money from any ABSA client and he has supported this by giving me an affidavit to support this and I have forwarded this same affidavit to miss/Mrs Sinazo Mbaliswana, the complaint management officer in charge of my case, but since that it has be an issue to reach her to get a response or an update on my case. Each time I call, it's either she's on another call, I will be told she will call me back, which won't happen at the end of the day.. This is totally unacceptable, as it goes to show that capitec bank is deliberately trying to frustrate me into forgetting this money.... All documentation relating to my transaction with Mr Okoro a capitec client, who transferred the money to me has being sent directly to her to verify them on her own..
