Don't by a Hisence TV from HI Fi Coperation

Bought a Hisence Flat screen TV, Pic sills appeared on the TV, reruned it to hi fi Corp, no calls, no feedback only one call after I had called, called them every week, have been in at the store for feedback, promised to call me back, yet nothing since 4 May 2019, Hisence is just as bad.
