Terrible Service

I just recently relocated and want to transfer to one of their branches which is closer to where i live now, however i'm being told i need to pay R500 transfer fees which i find ridiculous since they owe me R1000 for the 5 lockdown months were they were deducting. I asked them to take R500 from money owed but they refused, telling they will reimburse of my 5 months after my contract ends in November 2021
