Letter required for UIF benefit

I requested a letter from FNB a week ago in order to claim my UIF benefit. This was directed to the HR department in JHB. I also sent an email to the HR Manager, Keegan Naicker in KZN a week ago requesting his assistance. He responded on the day advising that he would request it form JHB. I sent him an email yesterday as I have not received any feedback as yet. He has not responded.
