Adidas — Sales promotion messages to my mobile

I have been receiving sales promotional messages frequently in my mobile no. (+[protected] from ADIDAS. Based on my bitter experience with the shoes that I purchased a few years back, ADIDAS enjoys a poor image in my mind. So, I contacted ADIDAS' Customer care around a month back, requesting them to stop such messages to my mobile no. Though the help line person indicated 48 hours as the time that would be taken for this action, I am surprised that even today (1st Novemeber 2020) I got a promotional message. May I expect speedy action at elast now?
