Since there is a transfer clause, you better make up your mind to accept the transfer or not. If you don't want the transfer and also don't want to resign on your own, just let the company take the necessary action against you. But first, tell your company to give you something in writing first before you give your decision. If they don't want to give, just stay put and do your work as usual as if nothing has happened.
