Cheque card app**** for 6 weeks ago

I app**** for a cheque card on my Dad's account on which I have signing authority on 23 March and was informed it would take 7 - 10 days. I had no communication from the consultant who took the application nor the bank, so after about 3 weeks I called the call centre (Home Affairs is better at resolving problems than yours) and eventually got hold of a team leader who tried to find out what the delay is. Its been over 2 weeks now since I last spoke to her and I still don't have the card or any other communication . I don't know what to do next.
