Attitude against these clients

This matter is related to another matter i am dealing with them but to put it short see the email below from there consultant Tatenda Dube who deals with clients claims who accidentally sent the email to me instead of his manager. Shows you how they see there client between staff and manager.

Good day Yasmeen , - This is the Manager from CMC

As discussed previously ,the below e-mail is the response from the client .

I called him just to try to be on the same page with him on what he is saying below ,he is insisting that we put it in writing so that he can take the matter further . From the previous e-mail I sent him I did mention to him that we are in “need” of the second quote . Kindly assist please as I have a feeling he wants to be one of the difficult ones and I don’t want to keep “entertaining” his excuses . From the consultant ( Tatenda Dube) from CMC

Thank you for assisting on my entertaining excusses from one of the difficult one.
