NO sense of Understanding

I purchased a Samsung Galaxy on the 2013/07/23, a warranty period of 24 months and register this phone under ADH (Accidental Damage from Handling). The phone was sent in the first time, on this was two faults - dented frame and battery not lasting. This was replaced after I requested this to Samsung. This was the front glass Cover and the Battery. I was happy with the service then. According to ADH it still had one repair left, should the screen need to be replaced or for liquid damage. When I requested the call to be logged they said I would be payable this time. I requested them to go back on their records with the previous repair. My warranty on this phone is expiring soon and I just need the service I had the first time with them. And I kept on trying to explain and they failed to understand. I also said I would never buy a Samsung Product as I do not trust them anymore.
