No response

I have never in my life had to struggle with ABSA in the way that I have for the past 4 days. I am so disappointed with the lake of service received. The call centre agents are very helpful but the lady that is dealing with my application is always unavailable or on a call or she has left or something and when ever I leave a message for her she never calls back which is frustrating. I understand that companies are busy but how many times do I need to call before I get a response. I was advised that I will get an answer with in 24 hours nothing was done called again oh sorry wrong info now its 2-3 days which has passed and still no response. I am so frustrated with the type of service. How many times do I need to call how much airtime do I need to use to get a response from a person at ABSA. This is pathetic to say the least. I received a contact number to contact a manager in the credit department and again no one available to assist.
