Club Factory — cancel order as I placed order as guest

Address:

Visakhapatnam, Andhra Pradesh, 530026

Hi. My order number is s[protected]. Orderd it on august 4th as a guest so unable to cancel the order. Its first slogan birth day banner. Found a similar product offline so want to cancel that product. Couldn't find any scope to cancel it via website. So want to make sure that this helps to cancel my order. Please help me with this. As i don't want to invest twice on same product.
Thank you.
