Is it the rich getting richer by taking advantage of the poor

I deposited R1000 by into their standard bank account and I am a standard account holder

On requesting a refund I was only refunded R975. On asking why was I being refunded R975 I was informed by Feli via an email that the R25 is for bank charges. I then asked why the refund was done via ABSA since I was given different account numbers of their business of major banks in South Africa. If they had transferred the money from their Standard Bank account there wouldn 't be any charges.

I am aggrieved as when wanting to deposit the money, the customer service agent that took my call and sent me the account numbers never established what my electricity meter number is. Hence, I deposited the money being under the impression that they are my electricity supplier. I.was also never made aware that on transferring the funds back to my account there will be charges.

Surely they should also proof to me that ABSA charged R25 for the transaction.
