Headphone repairs

[Gaynor]

Hi all, I am not sure if this is the right place to ask this so please move if it isn't. I'm looking for someone in Joburg (I'm near to Bedfordview) who can repair a set of headphones. They were cheap but they're the most comfortable pair I've ever had. The only thing wrong with them is that one ear isn't working. They are iDance (brand) but I can't seem to find the range any more. Please contact me if you would be able to assist with this minor repair or if you know someone who can. Thank you
