bad service delivery

I was told after 6 months i could purchase a phone on account at The Truworths Claremont branch Cape Town. I was told by a call centre agent an ammount of R500 Must be paid in and the i could get a phone.The phone of choice was a samsung A10. When I went for the purchase after paying the amount of R500 i was told there is no stock and that stock would be ordered from Canal Walk for today.Now ive been told the order hasnt arrived and I must wait and to stop being grumpy. This service is very bad.I would like to know whre i can get the phone soonest.
