Bra's breaking after only 22 days

I purchased two bra's for R230(I think) at Milady's on the 26th May in Canal walk between 6-7:20pm and it fits but now the wire is coming out i ended up stitching the one wire on the grey bra because i only have the 2 that alternate from. The pink bra's wire is also starting to come out. I purchase bra's every time from you guys and within 1-3 months the wire gives issues or starts coming out. I hand wash bra's so it cannot be the issue as it can be hand washed. I do not have the slip of it also, i probably threw it away or something, but i am sure you can track a print out from the store. I would like it to be compensated for bad quality items and an exchange at my closest store for the same colour and size. I only started wearing it from the 29th May as i bought it as i was going away on holiday, so it was not worn from the date of purchase till the 29th May 2015. so i only got like 22 day wear and then breakage. Could management please assist. it is not a direct report for the store but for the quality of the items sold. <br>
