No Response From The Seller

I've been browsing and searching for someone that can make a custom design birthday cake for my daughter. I found plenty blogs and websites that said and offered those birthday cakes. But when I tried to contact them by email and sending short message services to the phone numbers that they listed on their websites, there is no reply whatsoever until now. Not even one seller that response to my question. I feel it so strange about it. Do they really want to sell online of their products? If they don't dare to reply their customers, why don't just closed their online stores and website so we don't have to see those unresponsive websites from the net. Really don't like this.
