Miller's RV Center Lie, delay and provide shoddy work and very poor customer service! Baton Rouge Louisiana

I had a couple of blowouts on my fith wheel that caused a need for some body work.  So I contacted Miller's RV to see if they could handle fixing my Keystone (they do not sell Keystone campers), they said it wasnt' a problem, so we scheduled a date to drop it off.  After a couple of weeks of not hearing back (I called and left messages) from them I went there.  That's when I got the estimate (dated the day after I dropped it off) that the service adviser said was supposed to be e-mailed to me.  I reviewed it and removed some line items that I would handle myself (due to their outrageous cost).  I was told I'd get a revised estimate e-mailed (again it was a no-sho).  I had to go there again after almost another month of nobody returning my calls.  That's when they fessed up to forgetting to order the material but,was now ordered.  I asked to see the invoice, it was dated that very day I was sitting there!  Three and a half weeks later and numerious non-returned calls, my wife contacts them to hear that it's been done for two weeks!  I go to pick it up and see there's a 3% charge to pay with a debt/credit card.  There's no way I'm giving these crooks another $50 on top of the $53 charge on my bill for "shop supplies"!  Shop supplies.....$53 for a handfull of screws!  I go to hook to my camper......Battery DEAD DEAD DEAD, landing gear won't move and the tires are all UDERINFLATED!  I had to jump off the gen. since the thing was sitting there for 84 days!  Yes, 84 days to do 8.5 hrs of work.  They'll lie right to your face while they're reaching for your wallet!  Some of the parts I told them NOT to order, I got shippd to my door for 1/3 of their price.  I understand mark-up and all but, don't try to actually steal from me and lie to me about it!  This place will NEVER see another penny of my money and I will warn every person I know to stay away from these crooks!
