Pathetic customer service-incorrect amount taken

Good day,

I have logged a complaint this week regarding an incorrect amount taken from my account regarding payment relief. I was refunded an incorrect amount as it should have been more. I kept calling the calling and then my log was answered Nthabiseng Sibande who advised that she will give me feedback today. I followed up twice today and now she advised that she is dependant on other business. How hard is it to do a calculation. I had app**** for payment relief because i needed it and now i have to beg for assistance from Absa
