incorrect info

I phone 3 times on different days to confirm how long it is going to take to replace a Samsung S4 mini screen. 3 times I have been told it is going to take 1 - 2 hours.<br> I booked my cell phone in on 17 October at Samsung Ilanga mall, Nelspruit, again, they confirmed 2 hours.<br> I phone today, 19 October to confirm if I can come and collect the phone @ 1pm, they said \ no
