Bad experience with Hurricane phones

Bad experience with Hurricane phones, 1st it was the Lynx and now it is the Hurricane curve. The 1st would not pick up network in some places at all, then I bought the 2nd on the 15 March 2019 on the 2nd week of purchase it gave me problems. It will go off while I am busy on the call or what's app, and if I insert a second sim card it will require pass word. I phoned Hurricane mobile for a refund as I don't want the Hurricane phone anymore. They can only repair it. They won't even give me a new one because the 7 days has passed. I want my money back not another Hurricane phone.
