Booked my ipad 3 times but not yet fixed

I boked in my Ipad 3 with a broken screen and the first round of service was quick and got a reply on 28 Jan that the ipad is fixed but it was not. clearly here was no testing done at all. I booked in again and then to my frustration after 3-4 when i went to collect there was another issue. I booked it again for the third time and this time they said they will courier it to me. I called them on Wednesday and the lady promised that it has been repaired and you will get the deliver by maximum tomorrow. But nothing yet.<br> I dont understand If they can not fix a simple issue why are they even in the service industry. <br> <br> Dinesh<br>
