if you were first owner of boxslots and person who started domain setup the service etc. and shit. answer the following.
if you want to run your own hosting company, why did you want to put a 50/50 partnership?
if yes, you couldnt pay or any other shit. the truth is, how did you trust him in the first place.
2. ok you made partnership with him, you only gave him the access and ability to change such information that you have mentioned, e.g. change owner transfer domain etc...
3. if he had done this in august, till then what have you been doing, to not notice such small issue if you care so much about your host? you dont care one bit to what happens, is what showz.
You only gave him the ability to do such things. Don't blame anyone else other than yourself.
even if proof is shown that rk tried taking over 100% of boxslots, just by changing owner, transferring domain etc... mind it, its your own fault only, nobody elses, as you were the one who put him in a position where he can do that.
Blame yourself for trusting such person, if you think he betrayed you!
