Bad customer service received from kwanda (accounts)

Bad customer service received from kwanda at the accounts department ,he was so rude on the phone today when i called back for the 3rd time with the same query which he was supposed to have resolved on the 10th march when i called the first time. Now i called back told me he has been waiting for his manager who is on lunch and when i asked why he has not resolved my issue he said "what else do you want me to say" instead of apologizing for the delay he was so rude about it and kept quiet at some point my account is up-to-date but my service are disconnected i need my app active. honestly thinking about shopping for another service provider nothing depresses than getting poor customer service.
