The Sales Guru order a product and paid in full and didn't receive the product or refund when asked for one Internet

I saw a curling/straightening iron on facebook and wanted to order one for my daughter.  I placed my order and paid $79 CAD to them.  I received an email stating they received my order and i would get another email once my order was shipped.  I waited about 3 to 4 weeks and nothing.  I sent an email to support@thesaleguru.com asking where my product was.  it is a automatic reply that states they are behind but the order would be shipped shortly and if i wanted a refund to email the manager.  I waitied another week and emailed the Support email again and recieved the same automatic respeonse.  Finally i emailed the manager and asked for a refund. I did recieve a response within 24 hours stating i would get a full refund within 7 to 15 business days. I wated and waited and received nothing.  I have email both emails every day with no response.  The support email cannot be delivery anymore as their inbox is full.  I recieved an fraud alert from my bank that someone was trying to take my off my card.  i eventaully have to cance my card and get a new one.  I tried emailing the manager again letting them know my card number had changed and to contact me via my phone or email so that i could get my refund.  I didn't think anything of it at the time, but i believe they may has tried to use my number.  I am not sure and cannot prove it.  

Bottom line, they are a rip off and it is unfair to take money from innocent people who are just trying to buy a xmas gift.   I would just like my money back.
