False Advertising of ADH Premium warranty

I Booked my phone in with liquid damage on 07/02/2015 and was told that it is in warranty and is covered by ADH for Liquid and cracked screen as I have not claimed any of my ADH premium warranty repairs<br> I get a call on Tuesday saying there will be a quote for the repair of my Phone as there is liquid damage <br> I informed the lady on the phone that I have registered with ADH premium and I am allowed a liquid damage repair FOR FREE (as advertised by Samsung ADH) and I get a response that ADH warranty is only valid if liquid damage is done to the MAIN mother board and my phones fault is to the SUB PCB board I informed the Lady that when registering with ADH that Nowhere on there website nor on their APP does it state that liquid damage will only be repaired if damage is to the Main Motherboard so according to their website my phone should still be repaired under warranty the lady replies saying a manger/supervisor will call me and Till Today I have not received any call from any manager or supervisor in connection with my phone being repaired and I am willing to take this to court if I am charge for the repair thanks to their false advertising
