ABSA INTERNET BANKING

reference number C-***2 , I'm so disappointed with ABSA internet banking, i bought airtime for R299 and it automatically converted the airtime to R1800 minutes, first i thought it was an MTN problem i called MTN and they said i have to call ABSA Ndivhuwo confirmed that they do not have that option on their internet banking but funny i have minutes that i do not need on my phone, ABSA is so outdated because even their call center agent can see that there is a problem but they cannot fix it on the spot, i have to wait 3 - 5 working days which is unacceptable seriously for an error that is not even my fault if ABSA has a problem with their banking app surely those technicians that re going to investigate should have seen the error,
