Loan Installment overcharged

I called capitec headoffice today 12 July between 11:49 and 12:29 to find out why my Access Facility instalment was increased in April by R17.98 from R6674.93 to R6992.91 and in June by R43.38 to R7036.22. I never used the Access facility funds since 2020. I called them to find out what is going on but I was transferred from one department to the other. I was cut-off four times.

The other agent then explained it was due to the increase in the repo rate. To my understanding the repo rate was increased once this year with 5 basis point but my installment was increased twice. I asked why and the consultant couldn't explain. He transferred me to the complaint department were I was even treated worse. I explained my query but instead of registering it and investigate, she cut me off.

I'm really disappointed with their unprofessional conduct to clients. I want my money back that I was unnecessarily overcharged

Thank you
