Sue them? Don't think so..TS bound to lose the case.
He signed contract (not got anot, he never said got, but on basis he signed a contract) but disappear without paying membership. He SHOULD have inform them in the first place. Not playing MIA then get hit with the consequences only cry this and that.

This should be common sense..inform when not able to do something. Unless he mentally retarded or a 3years old.

Typical malaysians thinking...never my fault. Its always the other party's fault.

Until..they are the other party.
