Replacement Phone Already Damaged

In April i had a replacement LG G3 phone, to which within 2 weeks the screen went black and not switch on, i was advised by Cellc Cresta to have it repaired and i took it to Cellc waterfalls park. they returned it as B.E.R, as the mother board had rust on it meaning it was exposed to water of which the phone never fell on ground or water from the day it was replaced. Clearly the phone came with the defect and upon use it deteriorated meaning it was not of any of my fault but probably the suppliers.<br> i spoke to Buhle at Finrite about it and emailed all doc she required for the underwriters to assess,after a month long of constant calling and pleading for feed back i was told that they can not replace my phone for no reason, they said i should take it up with LG on my own. Clearly now i don't know how this works but is this why i am paying insurance for????<br> WHAT I NEED IS MY PHONE WORKING/REPLACED i am tired of CELLC and FINRITE taking their premiums each month while i don't even have a functioning phone.<br> PLEASE GET YOUR ACT TOGETHER AND GIVE ME MY PHONE BACK!! I AM SICK AND TIRED OF YOUR NON RESPONSE TACTICS PERIOD!!!!!!
