Any proof from your work before? or what can guarantee my account is safe in your hands? I have 700 MMR how long to get 3500+ ? Thank you
Better to you to improve your skill first, if you are in 3 digit mmr that means your skill only in that bracket.
If you boost in to 3k you will just ruins other games also you will drop it again cause your bracket in 3 digit
After you improve your skill, you can make new account and prove yourself where you must be.
I think it doesnt matter as to this is a service. But the issue is if OP should have posts someproof of some of his work. Lets not be gullible. In terms in dota 2 skills. I think playing in your mmr bracket for month is better then create another account. It's not really advisable to create and create an account because you are just not contented in your mmr.
