Bad service

I am a regular customer at Ackermans and together with other customers who queue for a turn to be assisted, we are so unhappy with the service at this store. Service would be so slow with 1 teller, and if we are lucky that day it can be 2 tellers, though they cannot manage to speed up the queue. This affects us as customers as we go there also having other matters to attend to but one spends close to 30 minutes with ONLY 2 people in front of you. We will appreciate it very much if service at this store can be improved as this kind of service will also degrade the reputation of this branch; we may be forced to go to other branches where we will get good service.
