Clientele life and Clientele legal spam calls

So I am not a big complainer. I am usually very supportive of all types of businesses, big or small. My family has their own business but unfortunately Clientele Life, legal and all the other versions of the Clientele company has been making my life a misery for the past week.

I work the night shift on a popular international reality tv show that now has a local brand and for the past week i have been woken up every half hour by spam calls from Clientele. I have blocked the numbers but somehow they just keep calling with new numbers. I cannot silence my phone in case of an emergency on set or a family emergency. I am outraged by it and if Clientele thinks this is how they will get customers, they need to reevaluate their business strategy because this is absolute madness. How can you bully and harrass your potential customers like that? I never thought about getting life insurance and now i definitely dont want it just because of how the company does things. Is there anyway or anything i can do to stop this? I cant change my number because of work so please if anyone has any ideas to help me, i would really appreciate it. Like I said i have blocked thier numbers but they keep calling with new numbers every half hour and its really starting to tick me off.
