This is pure harassment

I keep receiving sms messages from Clientele Personal Loans long after I have opted out of their sms service. First of all, I never asked Clientele to contact me about any loan. I have unsubscribed to their database numerous times and yet, I have receive a weekly sms. On opting out, a message is sent that I will be unsubscribed but another message may come through but next week true and behold, another sms received. This borders on consumer harassment. My cellphone number is very personal to me and I have asked kindly that my number be removed since I am not interested in any clientele product. What is so difficult to respect people? Seriously annoyed.
