how do i get my stuff from a moving company who has delayed the delivery of the stuff by 6 weeks and still has no specific date of delivery ?

This sounds unreasonable.  Surely you are entitled to your stuff back.  You have a possible claim for either tresspass on chattel or conversion among other claims.  The damages for such include the fair rental value of your stuff or the fair market value of the stuff depending on the exact facts.  You must document your correspondence with the company in writing.  Oral conversations hold little value in court.  Either have an attorney send an e-mail or send a letter as soon as possible.  The lawyer should give the company a firm dead line in which your stuff must be returned.  If the stuff is not returned you could repurchase the stuff and send the company the bill.  However, before you do this contact an attorney to make sure the company is within your jurisdication, is able to be served properly and has the resources to pay your claim in event you prevail in your law suit.  If the company is operating in California and is a formed as a Corp, or LLC or LP you can go on the secratory of state web site and find the contact information for the agent of process.  Then you can contact the agent of process with your legal demand and or law suit papers.  If the claim is less then 7500 you could file a smal claims case.  Small claims is much eseir and less expensive then traditional civil court.   I'm sorry this has happened to you, it sounds llike an awful experience.   If you need additional assistance, I invite you to contact me.
