Still Waiting

I booked in my phone on the 25 February for the reason that It could read the sim card, then I get told because of a crack on the back of the phone I have to place an insurance claim to repair this for R3165 when I can get a Xperia Z2 back cover for R100, then they stated that the display frame would need to be replaced as well which I have no clue as to why this would need replacing as well. This is all good and well they as I have informed Cellsure of this and should they want to take the matter further that's there issue, but now I've paid an excess for something that should fall under warranty as my problem with the phone is not a hairline crack on the back of the phone but rather the phone not being able to read the sim card. It is now 17 March almost a month later and I get a message that they are still waiting for parts when I was told it would take a week 2 at the most to repair the phone.... HOW MUCH LONGER TILL I GET MY PHONE BACK FROM THE REPAIR CENTER???
