Is it still under warranty, Do not walk away,stand your ground, You paid good money for it and you want it to work . Complain,document all the times you've had it in the shop and make that salesman wish he had never heard of you. Tell them you no longer want a repair you want a replacement or money back if they can't deliver on their promises.Do not go away quietly.

Press the issue hard and let the shop know you intend to tell all of us how they choose to fix the issue. Let them know there are 30,000 members here and more than 9,000 visit daily. I am sure they will take notice of you...if not contact Brother directly. Is there another shop in your area? Perhaps they could help you work through Brother and get a new machine.
You paid too much money to have a lemon.
Stay strong! We are behind you waiting for their answer.

Hi Deanna, I'd stand my ground if I were you and constantly hound them to give you a replacement machine seeing as you've had so much trouble. As others have said you've spent a lot of money on the Embroidery Machine, so keep chasing them up. How long have you had the machine? As it's still under warranty I'd ask them to return the machine and give you a replacement straight away. Love Chris

I have the same machine. I'm not great at using it but yours sounds like a defective machine.

Oh, I feel your pain...Has your dealer ever sent your machine back to Brother to have the look at it? If not...they must do this after all of your trouble. I would contact Brother directly and supply the with a list of the repairs that you have had to have done and insist they get involved to help you resolve this. DON'T BE A WUSS about this...stand up for yourself and don't take no for an answer.

I agree with all the other remarks. You have to stand your ground. Embroidery machines are expensive. Good luck. Sarah.

I feel your pain---I purchased a 780D from a dealer---when it messed up I took it back for service---they treated me like I was stupid---I have been sewing for over 60 years and machine embroidering for 10 years--they COULD/DID not fix the machine--780D is not a top of the line machine but it does what I want/need--I also have a PE150 and SE400--not high tech but they work when I need them---the dealer I purchased the 780D from just kept making excuses--I took the machine to 2 other repair persons---FINALLY found a guy 2 hours away who FINALLY fixed it and STANDS by his work and the store has CUSTOMER SERVICE!!!!!!!---the original purchaser refused to make up a class for me after I had foot surgery and tried to drive but the foot hurt so much I couldn't get there--after calling--anyway their customer service was NON-EXISTENT---it is no wonder they went out of business!!!!!!---As the others have said---you MUST STAND your ground and DEMAND that it be resolved to YOUR SATISFACTION--do NOT give up embroidery----like the rest of your fellow CUTIES we LOVE our machine embroidery and all of our other crafts and especially we love the look of surprise and love when the recipient receives our gift that we have made especially for them----God bless you.

You should be able to have a fun time stitching on the 4500D. I have that model and I have had it in to the shop on multiple times, and I will send it back if it will not do FSL to my satisfaction. If you know your design is of good quality and you are not happy with the stitching, it is the machine and it should be fixable.
