Great service and great concept

I was running short of electricity while out of town when I came across this site. Upon registering, I got immediate feedback in an email, followed up by a call to ensure that I had all the details I needed and to check if I needed help. The token came through within 5 minutes and no further unipin codes or messages needed to get a token. Simply enter into the meter, which I would get a family member to do without all of the trouble of buying vouchers and finding meter number. Amazing service, really quick and easy! I will never go back to buying vouchers at the shops again. Thanks!
