Sudden R8.50 fee per transaction out of nowhere!

Come on FNB - it's not even 01 July (date of new fees blah blah) and I suddenly see last month or two I have R8.50 PER TRANSACTION on my Credit Card. I use my CC for all my transactions as a pass-through account. You have cost me hundreds!!! I emailed the credit card complaints only to be told: "fees are R8.50 per transaction"... Okay so were the last 5 years of never having these per-transaction fees just a bonus... and why are they appearing now just before your updated pricing... is this going to increase even more now? You've honestly cost me a lot of money by suddenly charging these fees. And recently enough for me to notice... these fees are not applicable for previous months... so what is the real story here.
