Firsrtly,I guess you don't have 15 ads.Go in game,shout "B>15 Ads L/O"maybe around 20m@1.2~1.3m each.If your stuff that being hacked is cheaper than 20m,better to ... forget it.
Secondly,"I've been wait for 4 days",is that sound too long waiting enough for you,there are people waiting for months,years or still not getting solved,even I had a ticket that getting solved about 4-5 months waiting.It's depend on how sensitive your case are.Scamming is one of them,Do Not trust or hand over any stuffs except you know him/her IRL,better to take SS everytime if you do.It's your fault if you are scammed.Please give time to GM and provide any proof if you have like SS.
