samsung tv part of frame chipped out

On 3 jan 2015 i took my tv in because of faulty usb port, i then had so much trouble getting my tv back, but finally on 28th feb it was ready for collection,i expected my tv to be in the same condition as it was when i took it in besides that the usb port was fixed,but on monday 16 march i saw a chipped out piece in the frame i know its 16days later but after the hastle they put me through im sure they can help me out, the customer service is so bad, besides for the one girl Monique who helped me out but i missed her call Tuesday and she was off wednesday, but some guy helped me telling me that my complaint is a month late but its only been 16days later, i don't know what my rights are and if im entitled to complain, but after making me wait and messing me around for 56days im sure they can help me out as it was their fault my tv is chipped. I have been calling since Monday and they all say we need to speak to our manager, im really hoping i will be helped, very disappointed in the bad service.
