RCS complaints

Submitted a insurance claim to RCS in April . Recieved a email acknowledging claim and told card will be placed on hold until claim processed. Since then recieved several calls for payment made several requests to process insurance claim and then told then have no record of forms. Initial calls showed claim and card on hold on there system but then it all seem to have disappeared. Resent claim forms and emails about 4 weeks ago and told claim will be processed. But now been called by Blake and associates for payment as my account was handed over "apparently RCS group is owned by Blake & associates"???
