Bad service from direct sales consultants

I am so unhappy with African bank direct sales consultants, after trying for over 2 days to get through to African bank as I am full time worker and does not get time to go to the Branch, they disconnected my call then again put me on hold til I ran out of call credit, I spoke to tswarelo who disconnected my call without assisting me with anything, then got through to Timothy who showed he wanted to assist but then put me on hold till I couldn't wait no more... I guess I have to got to the branch... I regret wasting my time with these two and will definitely be calling to complain and if not dealt with, ombudsman it is...
