Honestly, unless he is being held hostage and his captors won't allow him any contact with the outside world, spend your money on something nice for yourself instead of a "contact prediction".
Calling and asking for contact predictions is just taking the place of processing feelings. You don't need to hang onto this guy. It's not the right relationship for you. He doesn't value you, treating you carelessly and badly by not communicating with you, but that doesn't mean there is something wrong with you. Not being up for pining away after a careless and indifferent man means there is something right with you.
You can go and do something that is good for you with the money.
