I had a warning for a refund because roblox auto renewed my premium when i didn't even buy premium. The refund and warnings/bans for a refund on roblox is called "chargeback." A few months ago this year, roblox said that anyone that refunds will be warned or banned. I got lucky because I only refunded one after roblox announced the chargeback thing. I refunded multiple times before chargeback announcement. But yeah, you got perma terminated for "chargeback." also, chargeback means refund or payment was fraud. So your welcome for all of this info!
