Nintendo want to charge me again for fixing same fault in ds?

How old is it as if it is in the guarantee period it should be repaired or replaced for free. If it is for the same fault that you paid for repair for before then they should repair the thing for no more cost as it obviously didn't repair it properly the first time. Try looking online for consumers advice and or trading standards who should be able to help. Good Luck!!

if you're in the UK try trading standards or CAB for advice? also, try writing to nintendo again - direct to the customer services manager at the uk head office. write a letter explaining everything you've put in your above post - make sure you keep a copy and send it recorded. give them a time limit to respond - say 14 days from the date of your letter - or you will be taking further legal advice (i.e. CAB/trading standards for shoddy work). might just tip the scales in your favour and get you an answer. theres probably a time limit for the guarantee of repairs - might be on your original paperwork. all i can suggest is that if you do have to pay again get her to play it almost constantly if there is a time limit, so you won't be stung again. good luck!

The thing is, from Nintendo's point of view they fixed it 5 months ago and you haven't complained about the problem again until now, which doesn't imply that it wasn't fixed properly the first time. It would be reasonable to assume that with no complaints until 5 months after a repair that the repair was carried out satisfactorily. I know you say that your daughter hasn't used it much since September, but do you know how many people probably try that to get a free repair. Ask them exactly what work was carried out in September, and whether it included replacing any parts. If they didn't actually replace a part then ask them what work they'll be carrying out this time. If they replaced the part then its unlikely you'd have the same problem with the same part without something causing it. Remember, unfortunately for you Nintendo are the experts and will probably be able to prove to you that the Nintendo was returned in working order in September. They are also probably expert in recognising if damage has been done to the hardware. I appreciate that you say your 8½ year old daughter rarely plays it and doesn't change the games often - but can you be 100% certain that on one of the occasions where she did play it and did change the game that she didn't try to put the card in the wrong way? Try contacting Nintendo CS and complain, but don't be surprised if they stick to their guns. You could threaten them with trading standards, but I'm not sure how far you'd get with that. You'll probably find a note in the guarantee somewhere that says that any repairs carried out to remedy physical damage will be charged to the customer. Additionally, due to the portable nature of the product I'd imagine the guarantee would be quite restricting.

if they fixed it you should find out if u have a warranty on the part they replaced if not if the ds is under warranty the send it bk to where u got it from
