I cant unlock my ipod touch

You need to recover the AppleID and passcode used to initiate the

Activation Lock on your iPod.

If you forgot your Apple ID  - Apple Support

If you forgot your Apple ID password  - Apple Support

or

If you were the original purchaser and can prove it with

a receipt from Apple or Apple authorized iPod retailer showing

the serial number of the iPod, make a genius bar

reservation and bring in the receipt, iPod, and government

issued photo ID to Apple and they may assist in resolving the problem.

If the iPod was purchased used or there is no receipt, the AppleID and passcode must be recovered 

It is highly recommended that you make a Genius Bar Reservation to avoid delay at the Apple store

Apple doesn't routinely monitor the discussions. Most of us are users like you.

If you are the original owner, contact Apple. Apple can remove the ID  if provided the required paperwork. 

Request additional support for unlocking your device

Either take the device, the original purchase receipt with the serial number, and a photo ID to the nearest Apple Store (if it has reopened). Call the store before going to make sure they can help.
