They are not an Australian company despite the '.com.au' and refering to themselves as BecexTech Australia. The business name was cancelled in 2011:

Their techsupport is only responsive only after having to send numerous requests for support and status updates.

I returned a phone which has faulty GPS. It was returned under warranty on the 15/16 Feb 2017. They quote a 2-4 week turn around. After returning to the first repairer they onyl found out after 4 weeks that they needed a spare part to fix it, so they are sending to a second repairer. They said the 2-4 week wait starts again which I disagree with. According to their website at the time, they quote 2-4 weeks turn around period. It shouldn't matter if they need to send it somewhere else. A further 1 month passes (so 2 months in total) they claim that the IMEI number on their records does not match the phone I sent back. I definitely sent the very same phone they sent out to me, I do not have another like it nor have I ever owned another like it. They are requesting that I pay an admin fee of $55 to return the phone without being repaired. I hadn't used the GPS on the phone until Nov/Dec 2016 but was only able to get around to reporting it in Feb, so as far as I know the fault could have always been there. Very poor business and now I am out of pocket for this phone. The fact that their support is very slow is enough to not buy from them, let alone everything else.

Sequence of events in 2017:
1 Feb 17: Sent email requesting help. Followed their troubleshooting instructions
10 Feb: BecexTech request phone to be sent back
16 Feb: BecexTech repairers received faulty phone at my cost
22 Feb: Requested status update, no update given
06 Mar: Requested status update, replied saying it takes 2-4 weeks for repair
16 Mar: Requested status update (4 weeks since they received phone), same response received as that given on 06 Mar
20 Mar: Received email saying "our RMA team that your phone will be forwarded to the 2nd repairer due to spare part issue"
20 Mar: Request ETA, they reply saying sending to another repairer will restart the 2-4 week process which I believe was not advertised by them in their warranty.
29 Mar: Request another status update. They reply back saying the IMEI number of the faulty phone is different to that in there records. They ask to confirm this.
30 Mar: I reply saying I sent the very same phone they originally sent me.
30 Mar: Reply from BecexTech:
We had checked and noticed that the IMEI number from the phone you returned is different with the one in our record. IMEI number in our record is 358394072727279, whereas the one you returned is 358394070479337. It does not match with the one that you returned to us.

Please advise where should we return the phone to. Also, please be advised that $55 admin fee needs to be cleared.

p.s: The discrepancy of the IMEI number should be reported when the phone was in our 1st repair agent's premises, but they never reported the IMEI number from the phone you returned. The discrepancy of the IMEI number has just been reported by our 2nd repairer.

30 Mar: Requested managers number and have received no response. Only to say they will not be working on this further.
