Unable to Deposit ZP

Right- after weeks of frustration and endlessley searching the forums I feel as if I need to vent a bit here.

First of all I am now unable to use my debit card in any capacity when trying to deposit ZP- I will constantly get "failed to pass security validations". Now I submitted a ticket and was told to contact support over at buddieshops. They said that my account had been temporarily blocked due to entering the wrong information more than twice within 24 hours, and that in recieving the email I was unblocked but with an imposed limit of $40 every 3 days. Now this is the part that REALLY irritates me- my furst debit card Zp purchase of 10k zp was succesful, and looking at all the errors people were getting I decided to copy and paste all the details I had entered into a secure file. (I stress secure so that people dont flame about it). Now when I went to paste the EXACT SAME details I get the error message- failed to pass security validations. Now I only have one try left- so i enter in my details without pasting anything in, double check with the copy I had- they were both identical- and I still get the error message! And yes I do have money on my card. So basically I have no idea what I need to enter.

Paypal similarly is giving me grief- my first payment was fine (50k zp no problem) and now I repeatedly get the error message "sorry your transaction failed to be completed" or something along those lines. When I first used paypal I had no money in the paypal account- instead it was drawn straight from the bank account which was linked to it- but after looking around the forums people often suggested having money in paypal itself. And so I put £20 and tried to buy 10k zp (worth much less than 20 pounds) and surprise surprise still got the same error.

Blergh- sorry for the rant.
I've given up on trying to fix the card issue now, and I emailed g4box about paypal (dunno if its the right email- still waiting to hear back from my support ticket I submitted).

I guess your all gonna suggest prepaid card? So I would like someone who actually knows whats going on to tell me whether since now both my card and paypal are blocked- can a prepaid card or redeem code be refused since the other two options are blocked?
