We are trying to reach to Aston customer service over one week ago by calling and emailing but there is no response! Is the company went out of business? We spent hundred of dollars for their product. They should prioritize inbound questions customer have, otherwise more poor reviews like mine will deter future customers. This is unacceptable as a business that they don't even reply to either email or phone call. We are so disappointed. Please get back to us if you see this comment!
