Poor response/turnaround time from ABSA

Although R1.10 might not seem like a lot of money, it is, especially if this is what happens to many clients or to yourself many a times. When a rich bank like ABSA debits such an amount from your account and you write to them with no acknowledgement and no response you wonder how save your money is with them. I am hoping that they come back to me to explain why they took that amount of money from my account for something that they are unable to explain.
