How does a Vanilla Mastercard (giftcard) Deal With Negative Balance?

Question

Hi, I just purchased a vanilla mastercard to try and keep my identity safe as possible when buying things online, but there must have been a problem with their system, where their calculation of what you spent it on is added 2 times shown because it is shown in 2 different tables, one about pending amounts and the the available credit vs debits.

As a result, it causes me have to have a negative balance from this miscalculation.

On the card holder agreement, it says I am responsible for this payment. So some of my questions are:

1) How would they actually charge me for the balance since they never asked about my address or personal information? Wil they track my IP or phone, or follow transaction addresses/information?

2) Since this was from a miscalculation, will they correct it or will it be arguable that it was a mistake and these extra cost was not suppose to be deducted in the first place?

3) Is there any way just to terminate this card to ensure there are no more transactions?

4.Once it passes its "thru period" and begins to deduct a charge, will this negative balance get worse if I or they, don't do anything about it?

5. And lastly, if I were to just try and settle this and get it over with by paying the negative balance, how would I do it?

Answer 1

Don't worry about it, I had the same problem but I was confused because I had double payments, one in credit/debit and the other in the pending column.  So all I did was wait because in the agreement it says it may take up to 7 days to process.  After 7 days the amount due went away and I had a positive remaining balance.
