sms spaming me even after I opt out

I am ****en tired of this company sending me sms about their stupid in store promotions and all of that ****en garbage. I do not know where you get both my numbers from, but I swear to God and on my life, I will get my lawyer to take legal action against you If I receive one more of your useless sms's on both my numbers. YOU ARE ENVADING MY PRIVACY! and according to my knowledge that is ******* beyond measure. I hope for your sake you will rectify this soon enough. ****** idiots.
