Failure as a manager

I've been having non stop issues with this company. About a week ago, we asked for cards to be topped up, I received a confirmation email that it had been done but when I asked the staff members to check some did not receive the funds. It's been a week of asking for feedback. The team leader Lydia Ngakane has been copied in all emails but clearly she could not be bothered about the fact that there seems to be *****ulent activity happening in her company. Furthermore when requesting invoices it takes 4 plus days. No one seems to care about this either.
