Quick to debit and not to deliver

After ordering a LTE router online, I was telephonically contacted (after I had followed up). The order was confirmed and processed. My bank account was debited on February 23rd. I have still NOT received the router. No customer service. Promises from the online customer care agents, telephonically and on Twitter, that the case has been escalated and management informed, yet no-one has come back to me. I view this as theft. Payment has been made and no goods have been provided. How long should one wait before opening a case of theft?
