Blocked my account & bad service

Have been making daily payments from my ABSA account for years. Tried to make a payment today but received an error that *****ulant activity on my account and that ABSA cannot make the payment.

Call centre agent said she had received a lot of similar calls today and transferred me to the ***** dept. Lady there said it was due to security questions being answered incorrectly. I explained to her that I haven't called them in more thank 6 months and I most definitely passed the last security check I did, as my issue was solved telephonically. She told me to go to the nearest branch. When I said I am unable to because I stay far from the nearest town she asked me to hold. I held for about 5 min and then the call dropped

I'm so irritated by this!!
