I finally received a response from Coinizy/Kardiz about the matter.
So how long did it take you to get an answer from Coinizy/Kardiz?
You may add me to the list of their victims. Four days and no response from their "Support Ticket" system even though it states "24 hours". Their "Chat with us" link is dead and non-functioning.
Coinizy/Kardiz meets all the criterion for calling this company a SCAM!
My loss does not meet the legal threshold for Felony Theft in my jurisdiction, so I am not wasting my time on them. Others scammed out of larger sums may want to follow up on this: Reading through their terms and conditions on www.kardiz.com I found:
"If you need assistance, you can contact the Card Support team at support@mychoicecorporate.com or contact the IVR at +44 113 320 0312."
I have received no answer from that email yet. The phone number appears to be in the United Kingdom.
Looking at the web site mychoicecorporate.com it might appear that Coinizy/Kardiz is reselling the services of this My Choice Corporate, or perhaps mychoicecorporate.com now owns Coinizy/Kardiz. Your guess is as good as mine.
