I recall a thread whereby a newbie initiated a charge with Instavolt and noticed his card was initially debited with a £5 charge. The responder explained that IV ascertains the card is genuine and valid by charging this notional amount at the onset - subsequently deducting the actual amount as consumed by the user. Clear enough. As a 'newbie' myself, I today I initiated a charge at IV and had my first attempt aborted by a message coming up when the charge appeared to start saying 'swipe card again - swipe card again', etc. Nothing happened when I did so several times. I then replaced the tethered ccs head back into the IV device and started the procedure over from the start. This time it worked successfully. When I returned home I checked my credit card statement and found that I had two £5 debits pending - and no reconciliation following the successful completion (ie. £7.25). I feel that something is either amiss here or IV will rectify this accordingly in due course? Any and all thoughts please!
