I made an order a few months ago. Everything was fine untill UPS lost my parcel

Then I had to wait untill UPS could arrange the problem with the insurance company, in order to refund the money to ctd, and then cdt could send me again the order.
Well. The last email I received from ctd was more than two months ago. It seemed that they were working in the case with the insurance documentation and so. But since then, I've sent three or four emails to them, with no reply
It's very very strange, 'cause they seemed quite kind and serious, but not replying emails after weeks make's me think bad...
I've had no time at all these last weeks and the next step will be to call them, but I first want to know if anyone of you have ordered something or if have any info from them. Maybe they've closed or whatever, I don't know
Thanks to all in advance.
