Vinca, thank you for all the support and help getting my package to me. Sorry I was not replying earlier, I have been setting up a few PC's and testing the new NIC I got from FS.com. Fantastic service and help
and going the extra mile to help me get my purchase from your services. I will be ordering from FS.com again after this experience and given me confidence to trust your Company with my future orders and tech help.
THANK YOU.
