Tired of have to fight for something I am entitled to!!PATHETIC!!

Really one disappointed customer right now. Been months without a phone spent hours on the phone fighting and got nowhere. Purchased a Galaxy S4 the screen is broken and wanted to have it fixed under ADH cover.. Samsung canal walk telling me I will get quoted for the repair as my invoice does not have the IMEI number of the phone printed in. I have even tried for months now to have it repaired via House and Home the place I purchased phone but it turned out fruitless. I have been trying to get the phone fixesd for so long that it is nearly a month out of guarantee. How disgusting is that! Never thought after buy such a reputable brand name I would get such bad service.
