Once again sub Standard (bank) service

So my son is working in the Netherlands. His Standard bank credit card gets ****med. He speaks to the ***** department (eventually after holding on on an expensive international call for ages) who tell him a new card will be issued and I (his mum) can collect it at the Bayside branch together with a letter of authorization and a copy of his ID. An unfun 50 minutes wait in the queue sees me being served. Only to be told by the employee that the authorization needs to have the id number included in the letter, and not just the copy. While I'm organizing this with my son, I then get told that the letter of authorization needs to be handwritten and posted. I explain that the last letter I received took 3 and a half months to arrive by airmail and so this plan is not feasible. I then get told to call the branch manager. Predictably no answer. Meanwhile subscriptions etc. are being cancelled. So Standard Bank tell me how to solve this problem.
