VPNGhost VPNGhost is 100 x slower, won't refund Internet

I tried VPNGhost and have had nothing but problems with it. I only get 0.5 Mbps download speed when I usually get 50 Mbps.  On 8/29/16 I submitted a ticket. After several days they quit trying to resolve the problem and told me to wait for a system upgrade. On 10/05/16 I saw they upgraded on 09/23/16 and I downloaded the new keys, but the problem was not resolved.  Not only that, but now I cannot even send email from my PC when VPNGhost is connected..  On 10/05/16 I opened another ticket explaining that it was still not working and asking for a refund.  They did NOT answer, but marked the ticket "Answered".
