Could you please tell me if you have deducted my monthly membership fee and my ZynEscapes Preferred monthly fee to my card ending 2311? Kindly update me ASAP. Thank you. Rich Solomon September 13, 2016 04:24 Why is it that on my billing info in my back office it says there that I had Insufficient funds last Sept. 10, 2016? When in fact I know I had $176.00USD left on my 2311 card I made as my Primary card for billing purposes. Anette Risnes September 26, 2016 15:07 Hello! Can you help me? : Can you explain to me why I have drawn so many times too much and what I have been deducted so much money for the Zyndio ? I would ask to be reimbursed all I have been drawn too much immediately.

In fact I got another charge of $59.99 from Zyndio for the Pro membership that I am not happy about. I need that money back and at this point I want my full membership cancelled.
