Monthly card fee

So my colleague goes to Mr Price Tygervalley on the 29/01/2021 and she tells them she wants to settle her account. They give her the balance owing and she settled it. Today she gets an sms saying she is R60 outstanding on her account. She DOES NOT like to owe anyone money hence she settled her account. She just went to the branch now to ask why she owes R60 if she settled her account in January and the lady told her that it is for the monthly fee of the card. WHERE IN YOUR LIFE HAVE YOU HEARD SUCH UTTER BULL****!!!!!!!!!! Also where on the slip that she got when she app**** for credit did it say that you will be liable for a monthly fee of the card. She is already battling and now had to give her last R60 for travelling fees to work to pay for this ****. This is not acceptable. If they had told her on that day if it was on that slip then i can totally understand the situation. But this is a *******!!! So either show her the proof of where she signed that she knew about this R20 fee for a damn clothing account card or show the proof of where they told her. This is one of the most honest people i know and i will be damned if she has to pay for something she didnt know about. I suggest you give her the R60 back cause no where it stated this. UNACCEPTABLE!!!!!!!!!!!!!!!!!
