Is regpacks.com Safe?

I am Fatima Fatehi .. I registered Via the conference website `` Urban Economy Forum 2019 '' which was held on 28- ***** in Toronto Canada "36 King St E, Suite 400 Toronto, Canada M5C 3B2" This conference relied on the Reg Pack application .. to register who interest for this conference Regpack is located in Oakland, California In the last page of registration in the application ordered me the amount of the conference is $ 700 and if i want the Purchase Protection the amount of this Purchase Protection is 36$ the total is 736$ I received a confirmation Message through email. from the Conference that the payment had been received in full but There was a problem in the message When I received a message confirming that I paid the conference fee and Purchase Protection..Appeared Red text box written in it " I contacted to the Conference Officer"Adiam Gafoo " regarding this but she never responded. I had an accident on 14/10/2019, so I sent a message to the conference official and notified on ***** via e-mail , telling her i can't attend the conference As stated in the terms of procurement protection in the application of Reg Pack .. It is in the event of the registrar had an accident i can refund my money.. I tried to access the settings of the Regpack account and clicking the “File a Claim” link next to their purchase for a refund However, “File a Claim” does not exist and you can check this from the registration site. I sent a message to the Reg Pack application to complain to them what got me( about Conference official and ignored me- The problem of the application that there is no button To recover the money) But the app's response was very negative and unhelpful Their response was: 1- Unfortunately, we at the payments team cannot communicate with you for security purposes. We are simply the registration platform that Urban Economy uses for their registration. You will need to reach out to the admins with Urban Economy for further assistance. We have also forwarded your inquiry to them. Then i sent them many message ..finally sent me second message: 2- (( Hi Fatima, It looks like this receipt was sent after your registration was paid for and before your purchase protection was paid for. You're showing paid in full at this time. Please contact account admin going forward, as we are a software company and do not interface with our client's users. Please reach out to Adiam at Regpack@ueforum.org. )) I sent to the application several messages to solve my problem .. But they ignored me and They ignored the application error and the non-existent button to recover my money. Your request (27537) has been received and is being reviewed by our support staff.
