Student account monthly fee

Absa team came to University of Johannesburg , Soweto campus to recruit us to open absa student account and if you already have an absa account you can upgrade it to private student account. I asked the team if they were any charges whether monthly fee , transaction charges or digital charges and team said no they weren't any charges and exceptions for upgrading it . They recently charged me R400 for monthly fee and transaction charges which I had enquired about cause I'm a student who uses nsfas so that amount of money is ridiculous. I went to the branch and they said they can't help since my student account was upgraded to private and I tried calling customer care they told me to go the branch so they can assist me but I'm still not getting the help I need and I feel absa came to our campus to **** us since they told us they are no charges where else when you go the branch they tell you there's nothing like that cause they are exceptions. Absa is ****ming students into opening an absa account with false information
