My credit score has dropped due to Capitec's incompetence

I am absolutely disappointed in their services. I have taken out a loan with them and my debit orders go off on the 28th of every month. I have manually transferred payment into my loan account on the 27th of August yet they still debited me on the 28th of August. It took me nearly 4 phone calls to get the debit order reversed.

After being successfully reversed, my account is now showing that I'm in arrears for 2 months. I constantly have Capitec messaging on WhatsApp to make a payment plan yet I have paid my loan up to date and this is possibly an error because they reversed the debit order, I am always told the matter will be escalated, yet it still hasn't since Monday.

This has affected my credit score drastically yet I ALWAYS pay my installments on time. Customer's should not be affected by the bank's negligence and incompetence.
