poor service from point of sale

The worst possible experience i have ever encountered 1stly they kept me waiting for a week before they could have my phone delivered so the whole week I had to stay at home waiting for a delivery that never took place i couldn't go to hospital for my check up at the hospital i told them that i am a cancer patient they couldn't be bothered now the phone has arrived and the damn thing doesn't work i cant seem to get a hold of them to get the sale they called on time but after sale care is perthitic
