Got a slap on my face again

Im fooled again today by Edgars Northgate I was told on the 18/06/2015 when I called to checkup on my phone (which is the replacement phone which I booked in for repairs on the 10/05/2015) that didnt charge as well within three weeks of handover, that is back from repairs I must come and collect it ,got to the shop today(21/06/2015) as early as 9h30am ,you wont believe this again the phone is a wrong phone and some components are missing and mind you this is the 6th week turnaround time without my phone ,which this 6 weeks was given after I was told prior my phone should take 4 weeks turnaround time in repairs,got mad to the store manager she promised to call the security to throw me out of her store she didnt even consider that Ive been taken back and forth since 07/02/2015 by the same store.I need help to get a new phone which will be a second replacement phone if that happens though or my money from Edgars I just cant continue like this this is BADE SERVICE at best.PLEASE HELP ME IM ON MY KNEES AND IM REALLY FRUSTRATED BIG TIME.Its the same HUAWEI ASCEND P6 which started to give problems as from 07/02/2015
