1. Be careful of the terminology you use. A ban is complete removal from the game. A RESTRICTION is a pvp matchmaking denial. 2. You do know your internet signal quality is never stable and can change over time due to a number of factors some of which you can control or correct. You were ruining match after match for others who reported you prompting Bungie to investigate you and issue a warning.... which from the sound of ot you ignored. This got you more reports and a second investigation which found cause for a second warning but this time it came with a restriction. You can try filling out the ban appeal form found on Bungie.net with a basic search for it or you can wait out your restriction and use this time to sort out your internet issues.
