FNB Disability Procedure

FNB has no disability policy for helping people on the phone. My mom is 78years old. Legally blind and hard of hearing. I repeatedly ask the agent Nosiphiwo Xaba to speak louder. She either was not able or did not care to. We ask to speak with a man so he could speak louder but they said none is available. I requested to speak with the supervisor Princess Makwena but she just told the agent they have their procedures. i am not allowed to help at all. But when the account was oppened i was allowed to help with everything. We will be closing this account tomorrow and move to a bank that understand people have disabilities and would rather help them instead of doing nothing,
