Sorry man dont think anyone can do that. You may be able to do it yourself via modding but it also increases chances of you being banned.

Contact rockstar and alert them of your situation and they would remove the cash for you, however I wouldn't sweat it THOUSANDS have a billion+ and no-sign of anyone being banned.

Worst comes too worse, just keep purchasing an adder and replacing it with a car in your garage, takes some time but hey it would get you what you want.

You won't get banned, dont worry buddy

Yes, I already reported it to Rockstar, unfortunately I've read that might be a bad thing. I'll do the adder thing probably, to reduce my money. CRM, are you positive I and others won't be banned?

unlink your rockstar social club from your xbox live there is a bot that rockstar has that will automatically put you in cheat lobby if it sees something out of the ordinary. same goes to all people hosting dont believe me ? Im in cheat lobby for 9mths on recieving money

if some one sets there cash multiplyer to -99999999 and set a bounty one some one any you had the cash in your inventory not bank that could remove it but it might not

Hmmm, sounds like it would be harder to mod the negative money, while ending in too many problems. I'll probably just buy the adder a bunch.

Don't report this to Rockstar as I am sure they will ban you. Unlink yourself from the social club if you haven't already.

Yes I just did. I hope I don't get banned or reset, I didn't ask for the money, but sadly I have no proof(Recording and I forgot the guys gamertag).
