Teespring.com James Unauthorized charges on my debit card Internet Internet

My debit card was charged $25.98 for an unauthorized purchase from Teespring.com. I made one purchase over a year ago from this company but none recently. I contacted and spoke to James who stated he could not find the charge anywhere on his computer and I would basically have to dispute it with my Bank. He was supposed to call me back after checking with his European partners but I received no such call to date. I disputed this with my bank and had to close my debit card which means, all of my bill pay accounts will have to be changed as well. I vow never to purchase from any seller on the Internet other than reputable companies that I know won't rip me off.
