Fnb transfers money without my consent and staff not assisting

I made a credit card purchase of R3200 on the 21st May 2020 and made payment "straight payment" on the 26th May 2020 but then payment was not rejecting on my straight credit card account. I then followed up with Fnb on Monday the 29th June 2020 and was told the payment was made to my budget. How is this possible Fnb when I did not give you the instruction to transfer payment into budget? And how many months instalment under budget did you make it without my consent? The budget installments are up to date and when I always make payment under straight I am able to pay straight immediately. I have asked your staff member to assist me since Monday the 29th June 2020 but nothing is being done. I asked you staff member Ryan Govender to give me the name of the person who made this transfer to budget without my consent and I am not being answered. I asked in how many months payments was this R3200 made under budget and still I am not answered. All this is done via emails, your staff is not even making a phone call. Is this the private service one pays for at Fnb ? Do you now just transfer funds as you please on peoples account to charge more interest without even contacting the client? This is shocking and *********. Is reporting on hello peter the only way to get professional service from Fnb ?
