Unsatisfied customer

Like i have posted few weeks back about this specific store. I went to the store today personally as technicians came to my flat over the weekend to check my fridge they said i should switch it off as the was ice in the deepfreezer so that they can assess it properly... I met with the manager, she was very helpful because she called hisense people about the fridge. But the thing is now they are trying to pin this on me as she said i waited over a year. I told her i came to the store 2weeks after i bought the fridge and that i made it clear that i want it exchanged. So they said the technicians should assess it and hisense will take it from there that's if the fridge is not repairable... But what the technician said to me was they have to do hisense and game a favor as they're middle man btwn the store and hisense. So basically what the technician was actually saying is they will do anything just for hisense to not loose anything bcz obviously exchanging that fridge will be a lose for hisense... This people are crocks please help me deal with this matter because this matter is draining me emotionally.
