Charged 4 times for a transaction that didnt happen!

I tried to purchase items on the online site on 24th November. The purchase didn't go through however my credit card was debited 4 times!!! It has now been 2 weeks of follow up and sending them my credit card statements several times as proof and Edgars has failed to resolve and refund. They never return my calls with feedback. Shocking and regrettably I am fearful of making any online purchases from Edgars because of this.
