ATM machine error-Withdraw R3000 but ATM dispatched R2000-capitec bank rejected my claim by text.by text ,I requested a formal email to send to my lawyers but still no response.

On the 25th Nov just before 19:00 I went to withdraw money from capitec Bank ATM Mall of the north,I selected R3000 but the ATM machine only dispatch R2000,I only saw it later when I needed to use the money ,I then called the branch and opened a case ,two days later they sent me a reject text,I then called again requesting a formal rejection letter by email so I can forward it to my lawyers to deal with the case ,till today I'm still waiting for the email and a form report of their investigation. Still no refund of my money either.
