The company are not under an obligation to release you from these restrictions in your contract, judging by the fact that they have sent you a cease and desist letter this would lead to the conclusion that they wish to fully enforce the restrictions against you.

Glad to be off assistance, I would include this in your response to the cease and desist letter.
