FNB ATM ****med Again and Again by their people who checks them and nothing is done about it😰😰😰

A client deposited R3600 into my account at Greenstone ATM which is my business account and it gave an error, afterwards and gave a receipt saying the deposit was unsuccessful but did not return the money. It was Good Friday so the banks were closed. I was informed by a client which I called the bank. They said I should go to the branch to complete the forms or do it online. Which the client came with on Saturday. I was told the case will be lodged on Tuesdays which was today and they will refund the money back into my account by Friday. Today I received a text to say they have accepted the claim and the money will be refunded into the account in 14 business hours. Later around 6pm I received a bank notification that R400 has been paid into my account and my client was the reference. I called to ask where is the rest of R3200 went to? The guy who was helping me at the call center said they usually refund the money found on the ATM. Advised that I visit the branch to find out what happened to the rest of the money. But knowing how FNB ****s their clients the possibilities of getting R3200 tomorrow or whenever they would have to return the full amounts are very slim. As they have stole from me before and never refunded me even a cent. Now I'm having same experience again and my worst nightmare is about to become real. My bank *****ing from me once more.
