(b) pay claims in a timely manner;
(c) provide proper notice, when required, with respect to the reasons for the insurer's failure to make claim payments when due;
(d) pay, without just cause, proper claims arising under coverage provided by its policies, whether the claims are in favor of an insured, in favor of a third person with respect to the liability of an insured to the third person, or in favor of any other person entitled to the benefits of a policy; or
(e) pay interest pursuant to 33-18-232 (2).
