More refund points

I used two refunds in my hole play time and seeing only having one left is annoying because i needed to use those 2 for repurching something cause i clickt the wrong skin/champ I would prefer it if we could have a generator system where we get everymonth or two 1 more refund credit instead of 3 through the hole game by making a simple 4th mistake you can regret it for bying the wrong skin or champion and that's really frustrating for some people I myself hasn't got this problem but I have friends who had this problems. so a generated system would work better imo
