No help after numerous calls and emails back and forth

To whom it may concern I hope that the management of home choice can contact me because I'm tired of agents calling me that sounds so unprofessional on the phone either like they just woke up or have no appropriate way in talking to customers and acting on the phone as if I'm stupid and don't understand what's my issues all about I need a technician to come and see my machine I have papers to state it's got 4 years warranty

Hisense Repair *** this is my reference I
