no call back / bad attitude

on the 19th July i handed in my Logitech gaming mouse to the IT department. Devan booked it in and told me specifically he would get a reference number so that i can be credited the next day. this morning the 20th July I call just before 12 as he has not given feedback as yet, he tells me he is still to receive a ref number and they he will call me in a few min. A few min did not happen. I left work Early from Montague Gardens to Paarl as surely it should of been done. I arrive just before 5pm. he hasnt done a damn thing as yet. I asked him why he doesnt have a ref number as yet then he says something that makes my blood boil... \it normally takes 10 working days"! how dare he say that when he told me it will be done the next day!!! they even discussed how long is the warranty of my product which is 3years"
