Digital Outlets thief! Internet, Calif

I ordered a Canon lens but received a Sigma lens.  I returned the Sigma for a refund, but still do not have it.

The order was on 11/6/14.  I sent it back on 11/12/14.  The Post Office tracking service says it was received by Digital Outlets on 11/14/14.  I heard nothing from them for a month.  Then I started to call.  At first it was that they didn't get it back yet.  Disproved that.  Then it was that they did sent acknowledgement of that (they did not) but they would send another.  Received the acknowledgement on 12/30/14.

Still no refund.  Another call to them.  Refund would be sent and I would receive it by 1/8/15.  On 1/8/15, there was no refund.  Called again.  "Scott" says that it was sent on 12/28/14.  Curious problem with the date sequence, there!  He gives me a confirmation number.  I call the credit card company which says that there isn't, nor ever was a refund from Digital Outlets. 

I have now put it into the hands of the credit card charge dispute division.

Called to let Scott know what the CC company said and he hung up on me.

This as a company to keep away from.
