ADH cover

bought my Samsung S4 and was never informed of ADH cover and that i neeed to register for it, like really who wouldnt have such cover esp when its free, months later my phone is damage and went to store, told me a big story of 2500 if repaired by them, am now Hearing about this ADH cover from a pass by at work, ai really this aint on, a sale not something you persue its what happens to you while you are immersed in serving your customer.
