Pathetic assistance

I tried to have my phone fixed by ADH for two weeks now, the consultants on the phone are *********** and have no idea what is going on. The couriers come on all the dates that I specifically stated that I am not available. now I am being told that they stop after three attempts. how long do I have to wait to get my phone fixed by this company. so disappointed and this left a real bad taste in my mouth regarding Samsung and their services. Don't offer me a service that is impossible to use.
