STILL WAITING ON FEEDBACK WITH REGARDS TO MY TV. Pppr service

I took my TV in Game store Zevenwacht Mall on the 3 of October. After 21 days no feedback or phone call. Only that it was taken to technician. I then went back to do a follow up in the store and I was told I need to call NU world as they told me my TV is with them. I then called NU world as advised by Game store staff to do, they told me I must not call them, I need to speak to Game as I am mot their client. I then went back to GAME again and I was told I should be the one that calls NU not them even after I told then I called NU already and was advised. They then said they will call me on Monday and today is Wednesday and I haven't received any call and I have been doing follow with the store with no concrete information. And it's a month now my TV it's been with them with no feedback. The staff is rude and their service is pathetic, especially Game store customer service desk and NI world
