Bad service

I have been trying to update my address as I need to order something.. I have send the documents on Monday and it is Thursday already and nothing has been updated.. Also they can't process my order manually.. I am frustrated as every time I follow up to see if it was updated I get informed of a new number or new email address I have to send this docs to.. Absolutely frustrating how on earth does it take this long to update an address.. I want a Manager to phone me urgently as no ons is meeting my expectations
