I must wait because of their mistakes !!

When trying to get info on a third party claims that I have been waiting for Mametsi send the underwriter the incorrect information, the underwriter has been willing to pay the claim for over a week but because Mametsi sent the incorrect information through they are unable to pay. When I contacted Mametsi, she was telling a long story about what had happened and kept asking me to listen to her. When I got upset due to pure frustration she refused to listen to me and finally said she would contact the client to get the correct info, which is all that i wanted from her.
