POOR QUALITY OF MATERIAL

I purchased a bra and matching underwear from La Senza in Edgars gateway last year August. I paid close to R550 for both these items. Fortunately for me I fell pregnant and couldn't wear push up bra's until I gave birth in March 2015. I have worn this 2 items for barely six months now an they are worn out as if they have been worn for 6 years. I was extremely happy with the quality and fit of your bras but after this encounter I am slowly starting to question it? The wires have come out from the bra!!! I obviously do not expect you to take back the items however I'm am really upset about the quality. I have many other items from your store but they are all in good condition but this particular set I bought is off a very very poor quality.
