Star Technologies, Sistrum Stands and Audio Points - are they still in busienss ?

I hate to inquire on a public forum such as this but based on what has occurred over the past 6 weeks leaves me to believe that there may be an issue here. I contacted Star Technologies and left a message for the owner ; Robert on this phone back on November 18th or so of this year. I did not hear any response back and thinking it was Thanksgiving that he may have taken a needed rest. I called after Thanksgiving and left a message and still no response. I went to the Star Technologies web site and then sent an email thinking that this may be the best way to contact Robert using their web-site figuring. Still nothing and we are now going on three weeks. This is odd as I have done business with Robert in the past he was always very responsive. I called once more and left a message and got a phone call back about an hour later and I was delighted to hear from him. This all started when I wanted to replace the stock speaker spikes on my Wilson Benesch Square 5 speakers with his Audio Points. ( which btw are very good ) Seeing how the points are metric and I wanted to make sure that the spikes that I would be buying from him to replace the existing ones would be '' built '' correctly ; I sent him one of my spikes as per Robert's request ; '' Yes , go ahead and send me one of those spikes so I know I have the right size for your speaker ''.  So I sent him the spike one month ago …...I have not heard back from and even after 4 left messages. I left a message last week saying this BS …...just send me the spike back and I will mail you a check for all of your efforts and shipping. Still nothing and I want my GD speaker spike back !  So, if any one knows what's going on with this business it would be very helpful. Thank you in advance.
