Fair Price terrible Customer Service

I bought a new TV a month ago, which has faulty picture quality. I logged a complaint immediately and was told a Hisense technician would be in touch. 1 month later, no response to my various emails. Calls go unattended. No Hisense Technician has come out contacted me. I do not want my TV repaired. I bought a brand new TV that is faulty and I expect a replacement or refund!!
