CellularOutfitter Had to write RETURN TO SENDER due to no way to contact on their website. Now they say they never received. Out $51.48 CA California

Feb 8, 2018 I tried to place an order that totalled $51.48 but their was a problem with their computer & I was unable to complete it. So I placed a 2nd order that went through fine. When I looked at my bank account the next morning I found I was charged for 2 orders. I tried everyway imaginable to contact them but wasn't successful. Their computer kept going in circles & "Sorry, we couln't find this page. Several days later I was able to access their "RMA" but never received  their approval to return the item. Feb 20, 2018, the next business day after the package was received by me, I wrote "RETURN TO SENDER" on it and handed to my mailman. I got a response when I posted this on Facebook & have texts that it would be corrected. On April 20, 2018, the "Chat" bubble was finally operable & I REACHED A HUMAN BEING for the first time on their website. I was told that the package was never received by them & I needed to file a lost claim with the Post Office because the Post Office just stores "RETURN TO SENDER" packages & isn't in a hurry to return them. This company practices "NO CUSTOMER SERVI E" and doesn't care about repeat business. They preys on new ignorant new customers like me. I will never do business with this company again and for this small amount it isn't worth taking legal action.
