Realme — Realme x7 max has Network and Flickering Issue

I have purchased Realme x7 Max but I am really disappointed with my purchase, handset has network issue and screen Flickering problem. I think it's my wrong decision to trust Realme brand, it's only 12 days old phone and has so many problems, ever expected, seems cheap low quality phone. Please be a genuine company and help so that customers can trust your brand and purchase, hope you understand and co-operate
