Roller Brush for S7 Plus, 2 Pack

I purchased a Verslife S7 plus, cordless vacuum from you to clean my carpets. ..the vaccum that I received did not come with the power brush that I needed,just the rotating floor cleaning tool that i dont need..I have been trying to purchase your rug cleaning power brush in your online store..& but its not available. Are you still making them. ? Its been a couple weeks & nothing has happened. ..Will you please let me know what is going on,? Thank you very much
