Makro RCS missed payment listing.

I changed banks in February, my new bank swopped my debit orders for me. A few of my accounts didn't go off as planned on the 1/03/2025. as i noticed it i paid it via eft. Makro Rcs decided to list my payment as a missed payment, not late but missed which is incorrect. The payment was made. I phoned them at least 10 times to follow up, i emailed and nothing. I phoned them to say i made a manual payment on the 6th of March, on the 15th they were still sending me messages that i didn't pay for march even though i send the proof of payment. this is ridiculous now listing it as a late payment and affecting my credit score. please correct this asap.
