Verification failed

BANK VERIFICATION I tried to get bank verification with FNB and CSD the info at the bank is the same as per my CSD profile but CSD keeps on saying that bank verification failed (company name ,name and surname identification ) what irritate a person is that they cannot even give you prove that the information is incorrect or show you where the problem is they keep on telling you about Hogan system and the information is correct I don't think the problem is with FNB but the problem is with CSD and now I am loosing business because of this problem. Please assist me
