Datastore throttling but not going over limit?

I've recently advertised a game of mine and after about 4 weeks it's stopped getting players. A huge problem is when the server had 8+ players, my datastore saving system would keep throttling and loosing player data although I really don't think I was saving/loading that much. I used this load function once when a player loads into the game and I use the save function every 120 seconds and when a player leaves. I even removed the autosave at one point and I still got some errors. I unfortunately didn't look into seeing if I was actually going over the limit when the game had players but I highly doubt I was using that many requests unless over like 10 players were joining and leaving within a minute.

My code, it's a lot, does anything look weird about it? Thanks

    local function CheckSAVE()
        local success, msg = pcall(function()
            GetData = PlayersStats:GetAsync(plr.UserId)
        end)
        if success then
            if GetData then
                Coins.Value = GetData[1]
                Level.Value = GetData[2]
