Account suspended without any resolution 7 days late.

I did a online purchase last week buying stuff from clicks, upon supply my banking detail the transaction showed as unsuccessful and my account was suspended. I am trying for the last 7 days to sort my account with zero satisfaction. I am currently out of the country with no access to my bank account, so that means no access to my funds. Its my son's graduation and I need to pay for this, but I can't cause Capitec bank has no sense of urgency or fails to understand my predicament. I wonder if they were in my situation how would they feel, I am the only parent supporting them at this point. They have no other sources of income. And I only get back in December. I stated on my emails, my call yesterday its urgent. But still no reply or resolution to my predicament. Can someone just help me urgently
