Decofurn in Deco Park Northriding

I bought a bed at Decofurn in Deco Park around August 2017. The salesman asked me for my details for delivery of which I gave to him. The next thing, I get promo SMSs from them. I called twice and asked them to remove my number of which they say they will and they didn't. I still receive SMSs from them and I never consented to be contacted in anyway other than delivering the goods I bought.
