rude, calls at ungodly hour, no manners

I just received a call at 9:05pm from RCS and whoever called me was rude, sarcastic, not professional, argued with the client, inconveniencing, upsetting. According to the CPA it's ******* to call any clients after 7pm as you are interrupting family time. Secondly what happened to being professional and respectful? Thirdly I want a formal apology from the board of directors regarding this violation of my rights to call me whilst sleeping and be treated like a piece of **** by an clearly unhappy and unprofessional call centre agent. Awaiting your urgent response regarding this matter
