Mine was too and all I was trying to do was purchase a refill. I will def be contacting my bank to dispute this charge!
it happened to me a long time ago and ST kept trying to say they only charged one charge to my credit card but actually they charged it 3 times...... I had to have the credit card company remove the two bogus charges and now I know better than to try to use their automatic refill service that charges the credit card. I buy the refill cards at Walmart.
