Mojang account migration -Help needed

So I attempted to login to the mc client yesterday as usual but was told that I had to log in via my email because my account had been migrated by someone - not me. Plus when you migrate your account you can change the pass registered to something else. So basically, my minecraft has been hacked. Does anyone have suggestions? I've tried most things including emailing Mojang directly but they say on their website that they only started answering questions from the beginning of april yesterday , so not much help expected there. Could anyone please help? Greatly appreciate it.

I've the transaction ID too, if that matters.

So you can't log in on minecraft.net either?

That sucks dude. Mojang is so lazy with that kind of stuff, same with other corporations and junk. They almost NEVER email you back, and even when they do it's like 6 months later when you've already figured it out.

Tonkow can't sign in to .net either and ikr live

Ouch heres a checklist i normally use
Password same as any other accounts u have?
If so is it a socialize website?
What im suspecting is you may have a virus or someone hacked your account. Possible u may have just forgotten something

Think it over in your head u might come up with something
