Cant log in a ***** case pathetic service

I am so frustrated with FNB once again. I have an amount of money deducted from my account that I am unaware of what it is. Now I want to launch a ***** complaint. The problem is that I am unable to reach the ***** department. After 5 calls and spending more than R100 airtime all they can give you is an automated response that they have lots of people calling in. The service is truly pathetic and once again I experienced a similar situation just last month when money was deducted and I did not know who it was. I cant log in a ***** on their app so why is the function even available. So i must keep on spending my own airtime because they are too pathetic to get consultants to assist one. And as soon as you review their service on hallo peter then they can respond. Terrible terrible service.
