I sent a carb to them that they received on 2/28. On 3/2 I received a call describing what they had to do and a price. I approved the work and gave my charge card number. They said it would be shipped in 2 weeks. Starting on 3/21 I sent them 2 emails asking when I would receive my carb. No response. I started calling them during their normal business hours and receive a recording saying that they are not available. I left several messages. No response. I tried the fax. Line was disconnected. I received my charge card statement today and noticed they put thru a charge for $499 on 3/9. Their website says payment would not be taken until carb is shipped. I'm getting nervous. Are they still in busines?
