(3) Cause the telephone to ring or engage any consumer in telephone conversation repeatedly or continuously in a manner a reasonable consumer would deem to be annoying, abusive or harassing;

(4) Knowingly and willfully initiate a telemarketing call to a consumer, or transfer or make available to others for telemarketing purposes a consumer's telephone number when that consumer has stated previously that he or she does not wish to receive solicitation calls by or on behalf of the seller unless such request has been rescinded;

(8) Obtain or submit for payment a check, draft or other form of negotiable paper drawn on a consumer's checking, savings, share or similar account without the consumer's express written or oral authorization. Such authorization shall be deemed verifiable if any of the following means are employed:

(10) Knowingly provide assistance or support to any telemarketer when that person knows or consciously avoids knowing that the telemarketer is engaged in any act in violation of sections 407.1070 to 407.1085; or
