Payjustnow payment update

I paid my last installment on the 24th December which was due on the 25th December and the error message reflected on the app, yet the money was debited from my account. The payment was not updated as paid and currently it is added with additional charges/penalties. I sent emails and escalated on the live chat but nothing and no one has assisted or returned to me with the solution. Payjust now resolve your technical issues and stop being an inconvenience
