Terrible service!

My african bank account was blocked 1 month ago now...firstly I called african bank ***** about it and they had no information about the case and said they would escalate the matter so that an investigator would get hold of me. 2nd time i called, i got the same message. 3rd time i call i got the same message. ONLY ON THE 4TH TIME OF CALLING could someone tell me what amounts it was for and i submitted my proof of payments that they had requested from me and still no callback on matter was received. On the 5th time of calling they then told me that i had to talk to the bank where the money came from (nedbank) to sort out this matter....in what effing! world must your client go do the work the bank is supposed to do for the client! This service is without doubt, HORRIFICALY SHOCKING!
