UNVALUED CUSTOMER

4th of May I was caught in a **** called FINESSA. The message said if I didn't pay my outstanding find further action would be taken and an extra 15% would be added to my phone. I clicked the link, everything looked reputable, the amount was for R250. The site even had a visa security check mark. I had to verify on my bank app that I was doing this transaction for 250, once I verified, this link took R7568.35, way over my daily limit. I tried reporting it immediately. For 10 minutes I struggled to speak to someone, once I got through, I was told I was in the wrong department and the gentleman put me through to someone else who then hung up on me. My 2nd call i was told the amount couldn't be reversed, even though on my side it had PENDING in my account. I was told there was nothing they could do to assist me. NO ONE CONTACTED ME. I've been sending emails, screenshots and requesting assistance, NOTHING FROM FNB. However today I get a basic letter, no evidence, no investigation, just a blank apology saying as a VALUED CUSTOMER. they did no wrong!!! I'M APPALLED AND DISGUSTED AND FEEL MY OWN BANK HAS JUST DE*****ED ME!!! I want my money back!!!
