False missed payment report

Despite talking to, two Vodacom agents confirming that they experienced system issues regarding debit orders resulting in debit orders not going off they have reported me to the credit bureau for a missed/late payment which is absoluut ******* if you ask me because the fault was on their side, I've been trying to resolve this problem and get them to correct the information with the credit bureau for two months and nothing is being said or done, I'm now sitting with a false missed payment report that cost me dearly and will keep costing me dearly unless they can clear my name with the credit bureau
