Missing R459000 for three months

For three months I have spoken to 50 people in Nedbank and FNB. There R459000 went missing Nedbank did not send me bank statement nor tell me that they were not receiving money from me. I kept on paying using the reference they gave me only to find that I was paying on their arrears account instead of credit account. I had to come back twice in South Africa within 3 months to sort this issue. Nedbank saying money is in FNB and FNB saying it is in Nedbank. I told Nedbank several times to trace the money I paid in April 2020 when I was in arrears as the missing R459000 is in the same account but Nedbank completely ignored me until FNB told them to look in their arrears account. They have credited half of the money to my account and credited the other half to another person I don’t know with similar name as mine. They said they are trying to retrieve my money. The staff is so ***********, poor and **** customer service. They don’t care about their customers. They told me to trace the money with FNB for three months until FNB told them to check their arrears account where they found my money. If Tshepo and Lee-Ann had listen to me when I told them that the reference I was using was given to me in April 2020 when I was im arrears they should have checked with arrears account. They caused a lot of stress and loss of earnings. I had to come from UK to deal with this sjambok. So *********** and inconsiderate bank, no interest in their customers. I wish no one use Nedbank it needs to be shut down.
