Really Ampath - Marelize?

I received a SMS regarding an outstanding amount on my account, which was correct. obviously from an "no reply" address. when phoning the accounts department to ask for an invoice, it was said that i would receive it in minutes. Five calls later with the same response - and checking the email address, still no invoice. Yet Friday, another SMS... They hide behind no reply addresses and call centres. You cannot get in touch with anyone else to get a simple task to be done. Really not quality service - to put it mildly. Maybe the government services norm became their norm as well.
