Pathetic at problem solving

Been trying to close my account since May, so that i can finalize my financial affairs and move on to another country all I get is a Customer Experience merry-go-round from hell. The Customer Experience Call centre is a nightmare! every time I call or email I get a different agent and have to explain from the beginning the issue at hand and the lack of progress. There is no continuity and I 've no idea if the problem is going to be resolved, by whom and when. I have been very patient and accommodating in submitting all the documents requested so that the account can be closed and I get the balance of the funds left in account. African bank problem-resolution system is ineffective and pathetic.
