Did you set up/create the account on pc, then used that login information on the tablet? (then, ofc, the account is different from that you played with earlier on the tablet)
If you still have the level data on your tablet, you can try to create an account on the tablet, then login to warzone on pc. If not (and also if that membership you have is paid not the trial) you might want to contact Fizzer. https://www.warzone.com/Contact
Gota be honest, it would be easier to understand what you did if you cleaned up your grammar a bit.
