Poor service at Estates dept

ABSA Wills & Estates dept service useless / non-existent. My Fater passed away 2 1/2 months ago, and since I reported the estate with them, the person assigned Ithumeleng Tsinyane ********** provides no feedback when e-mailed, doesn't answer any calls, or returns any calls when you leave voice mail. This is unacceptable. I want to have myself appointed as executor instead, as the value of the estate is also not that much in the first place, but I can't talk to this person to start arranging this!!!
