Unlock and reset my passowrd in my mobile micromax - x550

[Micromax X550]

I am in very deep trouble, I changed password in my Micromax x550 and now phone is permanently locked and I can not open it because I don't remember password at all.

I searched internet to find reset code which can work on that phone but there was no help on even google. I searched for Manually reset Micromax mobile phone and hard reset mobile phone or even tried to search to factory reset code. There were many code I found but I can't apply as I can't dial number. It only says input unlock code.

Anybody help me please
