The worst service ever

My word, the customer service at Absa Stellenbosch is the worst. The consultant acted as if I was inconveniencing her by having a query. A simple question of where my money went is still not answered. They referred me to the bank statement which doesn't even have the answer as well. And the money is still missing. Question: if my account is overdrawn by R65. 73 and I deposit R1200 how does the balance become R834? The cherry on top is the cheeky email responses that I got from their online staff. And I took the time during y lunch break to call and find out what happened and the lady on the line put me on an indefinite hold. ABSA, nenzani lapho sana?
