Invens V12 Plus cellphone

The company that produces the Invens V12 plus phone are selling us ****. Its been 8 months since I bought the phone. It freezes, over heats and has adds popping up every 10 seconds. Videos take forever to play or if it places it gets suck and replays the same part over and over again. It switches off randomly. DO NOT BUY THE INVENS CELL PHONE BRAND!!!!
