No Response from eMail

I am currently overseas in the UK and I could not use my currency card initially, when I made a transaction it was rejected but the money was taken off of my card. I sent a picture and email to the info address as advertised on the Bidvest website and to date nobody has gotten back to me. This was from the 1st June.<br> <br> Now today I received a double debit on my card of something I purchased and I just do not know how it has happened. I can not send to the info address because of no responses rendering my World Currency Card useless as I can not trust it.
