Mothers Estate

Good day Nedbank, I have a problem. My late mother's estate has been lodged with you guys since May, but up to date the funds have not been released. WE HAVE SUBMITTED EVERYTHING REQUIRED BY STILL NO MONEY HAS BEEN PAID OUT. WE HAVE BEEN TO THE BANK AND STILL NO HELP WE CALLED THE CUSTOMER CARE STILL NO ANSWER. THIS IS SO UNPROFESSIONAL AND ANNOYING AND TIRING. IT IS SO UNFAIR THAT MY SISTER AND I HAVE TO SUFFER LIKE THIS WHILE WE HAVE MONEY THAT IS WITH YOU BUT YOU WONT RELEASE
