AIM not so smart TV Pick n Pay

I purchased the AIM 55inch TV on black Friday last year. I was assured the TV was a "smart" TV but since trying to use all the functions this TV has given me nothing but problems. No Netflix no YouTube. After asking for a simple solution I was given a software update and promised that this will solve the issue but somehow after the update the TV was much worse. This is unacceptable and I am very unhappy with the service I received from the staff at the pick n pay I bought the item at. I would appreciate a TV of equal size and picture quality as a replacement at no extra charge
